That looks lovely. I really like the classic black and red vibe

TZR looks smart to? Is that yours. Whose is the RD and the blue DT looks nice also!

I wouldn't risk it personally. Just save and get a legit one.

It's my understanding, that it's £165 for a reason. Engines on these machines are savagely expensive to rebuild.

Good luck though.

I know Yamaha around the corner from me are fussy with exhausts, but back street garages tend to be more lenient.

Prox are a good make, better than Mitaka (Not Makita lol they make tools). That Prox was likely to be a forged aluminium one, which is far superior than the cast ones supplied by Mitaka. But I ran Mitaka for years without any issues.

Rings don't just melt, there is definitely something wrong here and I would check this out before throwing a fresh piston and barrel out it.

Often you'll find it'll be down to fueling, lubrication and the like.

I find on forged components that the piston ring end gap is left for the user to spec out, so be sure you do that prior to fitting it all together.

Wow, for that sort of money you can find a complete one for sure

When you run out of oil you will put air in the oil pump system. This wjll need to be bled. As a result it is not enough to just put oil in.

@NINJA I think a few members on here had issues.

I had to custom fabricate up some parts to get mine to fit.

Don't get me wrong, bang on for the money.

The DEP isn't THAT bad. I was meticulous with it and rust spots formed. But it didn't rot.

@NINJA Stock pipe. The amount of weight saved by going aftermarket is probably where 90% of the noticeable power comes from I swear!

@Darty Agreed, but man it don't half weigh a ton!
