- In this video we tune the Ho version of the Yamaha R7 and compare the results with a de restricted and tuned Lams version. The Lams model is a 660 cc and the HO a 690 cc. Watch the video to see what we discovered.

Great video
Currently working on a lams r7, MVR pod filters with carbonsmith velocity stacks and a cam upgrade. Should see over 80rwhp
hello sir i just want to ask if the restricted r7 has a smaller cc engine than a regular r7 or is the engine size the same and it only has for example ecu throttle and air intake restrictions?
@@bg5jckkgjc884 the restricted R7 is a 660cc, where as the open class is a 690cc.. so only 30cc less which doesnt account for much.
There is a throttle plate restriction and an ECU map restriction.
Honestly theres only 1 or 2 horse power difference with the restricted version and open class after a tune on the dyno (with performance parts)
@@6tdegrees oh okay thank you very much
@@6tdegrees sorry for asking again but if i unrestrict the supposedly restricted r7 ill only have a few horses less right?
nevermind u already answered that mb
Make me realise the Ninja 650 Lams is in some a better base engine to modify. I’ve picked up a few damaged Ninjas to make into track bikes, the ninja throttle body is a lot bigger than the MT throttle body to start with.
Only have the throttle stop to remove to make it fully unrestricted. No intake restrictions at all. (Talking 2017 +)
Just wish Kawasaki will 270 degree it’s crank
So I have a lams mt07 from what I’ve seen from this test there is no point on going to the mt07 ho right
Would the change from LAMS to ho be road legal, and how much would the whole process would cost roughly?
It's actually a seperate smaller 655cc engine in the LAMS version, not just a chocked-out 689cc engine so it would cost a pretty penny. You might as well just buy the HO version and get your full licence at that point.
Megustaria saver q escape y q filtro le puso no ablo Ingles podria escribir El nonbre porfavor gracias

How would you compare this bike to the cbr650r?
You got a chance of not killing yourself on the CBR lol. I like the CBR you have to wind it up to boogie. The R7/MT07 has alot of ompf down low, I test rode both and ended up with the CBR it's a more relaxed seat position too.
I owned a cbr650r dna, de restrict and full system, made 82hp after tuned was a good bike
@@vincentkahulugan9814 I'm Gunna tune up mine in a couple of weeks. I find I'm tapping the foot peg impatiently waiting for it to get near the red line 🤣🤣
@@vincentkahulugan9814 82hp? Should have been getting about 90 with a proper exhaust and tune.
These motors also aren’t the same as the MT-07 HO motors. They’re built with sustained RPM in mind, which the regular HO motor cant deal with
Interesting, is that official information or are you surmising?
@@astrostrotch the lining of the motor is different, this was in response to how lean the factory motor ran with aftermarket exhausts and of many recorded failures if kept at a constant high rpm for too long - such as track riding.
@@BigCarKilla so the HO motors are more likely to fail?
@@thedude1590 No, he means MT is more likely to fail than R7. Yamaha also told me the r7 engine has more titanium parts.
I'm a proud owner of a YZF R7 Ethel n I no the restrictor is in the throttle r U goin' 2 do a video of u removing one of not can I get the intell 😜🌙
