Basically identical to WP Xplor forks save for thread pitch in a few areas like the lower 'compression' bolt on the bottom different pitch. Uses same WP 48mm seals so yea some SKF would work fine. I have always found the OEM seals on the suspensions on these to be....junk.

I dunno, my own personal reasons make me want to say no but I won't rule things out. Will say I do enjoy building new bikes out of the crate, that is an experience you don't get with many other bikes and wouldn't have found that out without trying these.

From what I see all should work since even KTM clutch gasket is the same.

I mean it's whatever to me, bike's working fine. I can make it work if I want and this was just a play thing, I just got a Rekluse because it looked fun to play with for a bit. More don't want others to try this since Rekluse has these kits listed for this bike on their website and I think they made some assumptions that this is a 'clone engine', it's very close but has differences. Many of my frustrations with this bike were less with the bike and more GPX. From my side I got into these out of curiosity, learned what I need so like Kove/CFMoto/etc that are copying other engines, if I ever run across one I know what to expect. Like GPX sells Kove and I don't have an interest in those, I don't have questions. With THIS TSE300, I wanted to see if this was a KTM copy engine.

It depends but to do it over again I'd probably have looked at a '17-19 KTM. There's nothing wrong with my bike right now but it took 2 months of work to get it running, both engines I received had issues. Got this bike out of curiosity and because I wanted 'new' but few months into ownership I'd done more work to the bike than I would have on a used bike. Maybe they improved things on new ones, I can't say, after I fixed the engine it's been solid for last 100-hours so that's good. Also I run into Chinese QC issues even still, went to install a Rekluse and the steel discs wouldn't fit in one engine but do fit in the other engine, thankfully I had a spare engine to test it on but this isn't unexpected on these bikes.

@SCakey What was wrong with the engines? The bike I'm looking at is a very clean 44hour 2017 ktm 300cx-w $5600 The other is a 2024 gpx tse 300 with a kd jet kit and a few other things with 88 miles on it guy wants $4500.

@@timofeypinchuk877 His might not have issues. Powervalves locked closed, waterpumps seep coolant lightly, seen bad piston rings on new engines and I'm sure very few have done top ends. For that difference to me the KTM is much easier to find parts going forward. GPX is 'the same' but different, various parts are KTM copies with different thread pitch so you have to replace more than you'd think to use a KTM part. They arent bad bikes just odd differences from KTM you dont always expect.

@SCakey but you're a fan of their 4 strokes, right? The fse300?

Can't re-tune the MT05.3 with this far as I know, that one wasn't supported.

@@SCakey i'll wait...thanks mate

Scrubz designs plastics come with decals so got KTM logos on it.

Quite the opposite from my experience, Gary goes out of his way to help people

I've never enabled it but most likely under Fuel Cutoff Testing -> HW FCO Limit Vehicle Speed. You could possibly also remove this under Hardware --> J1-16 Input Usage change to 0.

Thanks for your quick reply. Can you assist me on how to change the input usage to 0? It’s a jumper, a wire connection or anything else?

That's my personal thought, I would have been better with a used $7k KTM. Too many Chinese issues on these for the price and GPX seems to have moved onto Kove. Probably find these for like $3-4k used next year.

KTM open chamber instructions, others done better videos and in the maintenance manual. Standard forks, nothing crazy except rebound adjuster.

Copy thank you! I gotta do my tse250 fork seals soon and never done them! What size fork seals and what brand you Recommend?

Also how much oil🤔

@@sliceofbutter6766 Open chamber forks measure fork oil height from the top of the fork tubes without spring. You can change that height depending on what you want, think I had mine around 120-130mm.

@@sliceofbutter6766 only use skf dual compound fork seal set. They are highly upgraded heavy duty seals to compare to factory. I called up USA Motortoys in Utah ( gpx ) to order my seals for my tse300. If replacing, use upgraded seals to prevent issues. Little more expensive but worth it. About 80 bucks for both sides

Good info but on those Xplor forks they were basically turned out almost max, I could have changed fork height a bit or fork oil but eh, got different carts in there now that I like more. Think I might have been like 2 clicks in from max or something on them most the time. These videos would have been with OEM suspension and what I find on Chinese stuff is it's entirely hit or miss coming from the factory, you can rebuild it and it can be decent but from the factory....eh. Heard one guy got his shock rebuilt after 40-50hrs and had 50psi of charge in it, who knows if it was like that from factory or just leaked. I wanted to try KTech ORVs in these forks but wasn't in the cards with GPX. The squatting rear end might have just been the OEM shock, I have sag set around 35-40mm and rider at ~115-120. Also have no idea when the OEM shock really blew out, I really felt it at like 45hrs going up Red Cone pass, felt like a pogo-stick in back but maybe leaking before that. Will be revisiting these notes again though since I've been diving into suspension a bit more lately for the new year and setup is always important.

I didn't dig into that one the same, lucked into a nice WP shock on mine but what I see is Chinese suspension stuff from the factory can be hit or miss like maybe your nitrogen isn't fully charged, maybe it's not bled right, a rebuild can generally make it good. Now I kinda wish I had kept the SZC Linkage shock to take apart but sold it a while back. I didn't replace springs because I'm a small guy and geared up I hit the 155-160lb range.

@@SCakey im kinda new to this type of shock. I suspect the same with low pressure. I dont see any Schrader valve. Is it covered? I'm at 190lbs geared. Any idea what the stock spring rate is a base reference.

The balls expand a bit as you ride and basically 'fill in' to touch each other. I could see having weird spots in the rim if you try to subtract a lot of balls from the wheel, I'd drill holes through them before removing balls for harder enduro.

why would that be a concern.?

Go scrap yard ur probably find lots now

What tools do I need? I'm fresh from carb bikes. I have a 2022 GPX FSE 300R

Yea for $4k USD, I'd take that deal on these.

@@SCakey you’re the pro here. As a beginner I’m more convinced to get one now. Thank you!

@@Trialstoenduro-vz8iq Hah no pro, just a dude that rides bikes.

Hello, I didn't actually fix that engine with the broken case. I have thought of trying to find a good welder to see if they'd give it a try but I don't know how well any fix would hold up. I think any welding fix would make it so my cases wouldn't match as well for the main case gasket sealing surface. The 'fix for me' was getting a second engine from GPX and swapping it in. I use the broken engine really just as some emergency spare parts.

@@SCakeyWhat did the new engine cost?
