    The road to the temple reminds me of the county roads in east Texas. They're very narrow but almost all of them are paved. Most of the county roads in west Texas are just dirt or gravel, fun to ride my XT250 on but the bike gets very dusty. Your videos were making me want to try a one tooth larger front sprocket on my XT250 but I'm worried about affecting it's hill climbing ability. I just found out this week that Suzuki will be making the DR650 for a least another year so I'm going to trade in my XT for a new DR650 in the next few weeks. I lke the simplicity of the DR, it's air/oil cooled, has a carburetor (no electric fuel pump to go out), it's reliable as a hammer. I bought a new DR650 in 1998 and put almost 30,000 trouble free miles on it before I sold it.

      All the small bikes here in Thailand use the toe/heel shifters and I've just gotten used to it by now. I use my toe on both of them, either shifting up with the heel or down with the toe, I've gotten use to it. Makes things a little hairy when I get on my Triumph though........

      Ever since I got this bike, I've said the engine needs more power. Since then, I've been looking at big bore kits and gearing to see what will work best for my riding up here in Northern Thailand. I have to travel some distance to get up to the mountain ranges to visit the places we want to go see, so I still need to be able to run close to 90 KPH up to the mountain areas. Once I'm in the mountain areas, I need the engine to be able to pull from down low in the RPM range and allow me to run at least in 2nd gear up the twisty roads. I really thought the 14 tooth sprocket would be perfect if I could get some usable Torque and another pony out of the engine. I believe we are at that stage now, I'll be finding out in the next couple of days....... Thanks for the comment, glad to see you agree....... Adding to this comment, I put the 14T back on this morning and took it for a short ride. That is the sprocket that will stay on the bike now, it works really good.....

One, he doesn't have the inexpensive access to the accessories like I do here, I'm pretty sure he would put this kit on if it didn't cost him an arm and a leg. For around $30.00 US he did what works for his riding area. It just wouldn't do for me here, I needed to be able to ride 75 to 80 KPH for some distance before I get to the really steep stuff, he only has a couple Kilometers to go and he's in riding heaven.

    The 15 tooth sprocket also might regain some of the lost fuel efficiency with employing the big bore kit and sure would seem to be the best combination for the highway rides leading to the trail rides. Question being of course does it underperform compared to the 13 or 14 when on tough trails and hills. From your ride today, the 15 tooth handled that temple hill, no problem. All depends I guess what you value the greatest but either way, this is a no lose endeavor. This bike handles and performs great, pure fun. Thanks.

      We currently have no plans to put a larger BBK in any of our bikes in the group, so we really haven't even searched for them. I know there are some 162cc & 181cc kits here in Thailand that are made for the Honda Wave 125i, which should fit the Honda CT 125 Gen 1 engines but there currently isn't any for the Gen 2 engined bikes here. As for sending a link, I'd have to do some serious research on them before I'd recommend either of those two kits. I've heard the 162 cc kit is pretty good, but we have not researched them at all. As for the 181cc kits, I've heard they like to go BOOM. Could be because most of the people here who put that kit in their bikes use them in drag races..... We may in the future do another build on a Gen 1 CT125 and when we do, it will probably get the 162cc kit in it, which means I'll be doing some serious research before we settle on a particular kit. As of now, there are a few Japanese companies that sell the BBK's for the Gen 1 CT and you can find the names and web sites for them on the Internet. Use the Honda CT125 in the search bar when looking..... I really can't tell you any more because we haven't spent any time on anything bigger than the 143cc kits we are using....

    I'm interested in how balanced the engine is with the bigger bore that and the mileage. Back in my day I had a Triumph Bonneville ... it would vibrate it''s nuts and bolts off if I cruised over 55 mph. My little Honda CL125 twin just purred and did 70 mph .. I never thought about gas .. did over 100 miles of power line roads in Arizona on less than a tank.
    Did you say one really needs a bigger bore exhaust with this upgrade?
    I don't see a listing from Honda on this kit. Could you tell us what kit you used and there? There seem to be a number of kits that will fit.
    Your videos are really a big help.

    • @TeamDNFracing
      @TeamDNFracing  4 ปีที่แล้ว +2

      Good questions: The engine is typical Honda with little or no vibration, even after installing the BB Kit. The fuel economy in stock form is on average 60KPL (Kilometers Per Liter) on all of my Adventure rides so far. Have not done a fuel economy run with the BB Kit yet. If you put the BB Kit on your bike, to get the full benefit of power available, HP & Torque, put a good free flowing air filter like a K&N and a less restrictive exhaust system on it. I have installed an SKA air filter, a Diablo full exhaust system to go with my big bore kit. This BB Kit is not from Honda, it has Genuine Honda parts in it, but is a kit put together by an after market speed shop here in Thailand. They do not ship over seas, someone has already tried. There are many kits that will fit this bike. The Grom, Monkey and Super Cub all have the same top end as the CT125. A hop up kit for one of them would fit the CT125 just fine. Make sure any kit you get has the larger fuel injector in it and I wouldn't go any bigger than a 150cc kit. I know they make them as big as 180cc, but I've also heard they are having trouble with the larger kits. Don't know what those problems are, but I don't really think you need anymore that 150cc for this bike. I'm really happy with the way this one is performing so far.....

    • @TeamDNFracing
      @TeamDNFracing  2 ปีที่แล้ว

      Thanks for the comment and a great question. The BBK gave the engine the low end torque it needed to pull hills. Sadly, it did not increase top end even with the 15T sprocket, but it did smooth out the overall power through the gears with the 15T sprocket compared to the stock 14T. What I mean by that is it was less of the high RPM pitch whine when it would top out in a gear. I didn't gain any top end speed with any gearing adjustment with the BBK installed. However, I later installed a Hot Cam and had the ECU re-mapped and that brought out the higher HP this engine needed. To top this off, I had the head ported and with those added to the BBK the bike just sounds like it wants to scream. Before these last additions, it was a struggle to hit the high 90's KPH with it which is still less than 60 MPH. With the cam, porting and ECU work done It easily pulls past those numbers and the highest I've hit is 109 KPH with the bike still pulling strong but I ran out of straight road and I have not desire to go that fast on this bike..... My fuel economy has suffered some with these additions, but not so much that I can't still run well over 200 Kilometers on a tank of gas...... Hope this helps you out......

Love the Trail 125 in concept and execution, the problem I have with this bike is it retails for $4000+ in the US, all of these improvements you're adding are great and realistically needed, but they cost even more $$$..... bringing the real cost to over $5000 USD. In that price range you can purchase some mighty fine bikes, including the Kawasaki Versys-300x which does everything the Honda can, but twice as good.

      Don't really need to do anymore speed test. The bike won't go much over 60MPH and I don't want to stress out the engine as it still is just an itty bitty putt putt bike. Don't get me wrong, I love this bike, it is perfect for what I want to do here in Northern Thailand, but it will not go fast with the set up I have on it. To get more speed, it will need some cam work, some ECU work, some intake work and someone with the knowledge to set it up just right for the speed. I don't possess that knowledge and don't really want my bike to be a hot rod, just needed more low end grunt for the hills... I've got that with the BBK, that was enough for me.....

      A smaller front or larger rear sprocket will reduce the bikes top speed but acceleration and climbing power will improve.

    • @TeamDNFracing
      @TeamDNFracing  4 ปีที่แล้ว +2

      I see someone left an explanation on what we are doing. Let me elaborate further on it. We are trying to optimize the power available on the bike to make the type of riding areas that we live in easier to ride. So, if you take the stock gearing which is as follows. A 14T front sprocket and a 39T rear sprocket, that makes your gear ratio which is 359. It is actually .359, but it is always expressed as 359 gear ratio. If you make that ratio lower, you will be able to climb steeper inclines with the same Horsepower from your engine. If you make the ratio higher, you should be able to run faster with your engine. So, when we put a 13T sprocket on the front, it lowers the ratio to a .333 and means that the engine turns the countershaft more times to power the rear sprocket one turn, that gives you more low end which allows you to climb steeper grades. Hope this answers your question......

      @@bts650 True. But a front sprocket costs about half what a rear sprocket costs and a smaller front sprocket weighs less. And sometimes if one goes for a really big rear sprocket they'll need to buy a longer chain. Longer chains again weigh more. Also a rear sprocket is a lot more labor intensive.

    Very concerned about vibration after big bore kit installed, what is your take on this?

    • @TeamDNFracing
      @TeamDNFracing  3 ปีที่แล้ว

      This kit is made up of stock 125cc parts. Some from Honda, some from Kawasaki. The parts are just being used a little differently from the manufactures intended purpose. The Kawasaki piston is bigger around than the Honda piston, that is how they get the extra cc's. Kawasaki uses the same design of an engine as Honda, only they use less stroke and a bigger diameter piston. Some smart guy over here took the larger Kawasaki piston and put the Kawasaki sleeve in the Honda cylinder and bingo, 142cc instead of 125cc. I've got no vibration from the engine and so far, no engine problems and I've got over 3,000 Kilometers on it in some pretty gnarly riding areas. Now, if you're thinking about the larger 181cc Big Bore Kit, I'd do some serious investigation on it first. I've heard some horror stories here in Thailand how they've blown parts all over the road when they blow up. The young guys around here put the 181cc BBK in for drag racing, so maybe it's just the racing part of it, but I've also been told by a guy in the states who put one on his Monkey and it blew up after a short while.... So be careful what you put in yours, and I'd feel safe with the 142cc kit, mine works great.....

Would a big bore kit compensate for my weight, or do you think a sprocket change would be necessary too?

      @TeamDNFracing  2 ปีที่แล้ว +1

      This kit is made up of stock Japanese designs, a combination of Honda and Kawasaki components. They include a stock Honda cylinder with a Kawasaki designed sleeve, piston and rings. So far I have had no problems with the BBK in my bike. However, both Robert and Daniel have had an engine knock issue with there bikes when put to extreme stress situations. We have also found out that the engine in the Honda Wave (which is identical to the CT) is also having the engine knock with them. The engine knock is more of a pre-ignition knock if you understand anything about combustion engines, you'll know what I'm talking about. It appears the problem is caused by to high of compression in the engine by installing a much larger piston and cylinder sleeve. On my bike, I had the head ported, which put a larger head combustion area and in turn lowers the compression. Roberts bike is in the iTimgarage shop having his head ported, a Hot Cam installed and a ECU from a Honda Monkey installed with a re-mapping of the ECU to improve overall power. These are the same things I've had done to my bike and it literally rips now. Easily will run well above 60MPH and the low end torque is now very usable. Robert is on vacation right now and when he returns in another week we will get his bike and do some serious testing with it. If he has no more problems with the engine knocking, then Daniel will take his bike to iTimgarage and have the same things done to his engine. Reliability wise, I have had no issues with my bike at all and I have over 7,000 Kilometers on my bike since I installed the BBK and I've put it through some very nasty terrain..... Hope this helps and we will be doing a follow up video on the performance of the mods we've done on the bikes.....

    Mixed feelings on big bore kit. I see how extra torque is helpful, but also wouldn’t want to sacrifice the refinement and durability of Honda engineering. A reasonable overbore (like you did) is probably key- don’t need to over stress the bottom end or have the clutches slip. I bet the 14t and that extra power will work out well with how you use the bike.
    Still, I wish they put the low range on it. You could run 15 and have extra speed on the road, flick the lever when you get to the trail and have gears equivalent to a 13t.

    • @TeamDNFracing
      @TeamDNFracing  4 ปีที่แล้ว +1

      I did a complete set of test runs with the 13T, 14T & 15T sprockets. The 13T gave it snap and power to climb, but suffered on top end. The 15T made the flat land road rides smooth, yet the engine would not pull 4th gear even on the flat lands and then the entire time on even small hills it just went flat. The stock 14T would pull 4th gear well, but still flats out to soon and suffered on steep inclines to the point it would just stop turning the rear tire. A basic stall out, which is not fun on an off road steep hill as with the automatic clutch, when you chop the throttle, the bike will role backwards down the hill. Sucks when that happens. After I installed the BB Kit, I did the same tests with all three sprockets. Big change in all three. The 13T had loads of snap and power, but still revved out to much on top end. The 15T pulled in all four gears very well and even climbed fairly steep mountain paved roads well in all gears. However, the stock 14T did everything very good and runs great on top in 4th gear and shows really good power in 1st gear on steep inclines. Honda should have just made the bike with a 150cc engine. Problem solved.......

      Yeah. I’d hate to buy one, then have that happen. I doubt they will come out with a low range, as changing casting dies would be prohibitively expensive. I suspect the low range on the Trail 70, 90 and 110 was more of a happy accident, that the feature was seen as necessary on the ATC 110 and other 3 wheelers that shared the same power plant.
      These days Honda seems disinclined fo offer low range. Their top quad the Rincon 680 would be more versatile if so equipped, as would their Ridgeline.
