You know since how long this was cooking man. Yeah its finally out.



I will give some figures after we dyno the bike and do some testing with the speed gun,that should give a clear pic of whats happening.


Update
So far 780kms done after the engine rebuild . And the bike is feeling better day by day .
Good to know and read all of it..Keeping an Eye on it and
waiting for more!

@silver_falcon - FYI, there is no R15 race class. Its the Group B 130cc to 165cc 4-stroke class that you are referring to.
A 60mm piston on the R15 will make it 165.8cc and does not fit the class. You will get disqualified for even breaching 0.8cc.
However this big-bore has been tested extensively on our R15 and it has already surpassed a 2500kms reliability test and add to it a trackday with the highest possible abuse.

Good stuff. 2500kms reliability test would be the more valid point for touring. FYI, the R15 class race was information from Navnish .

I heard Navnish would be touring extensively very soon. 800kms in one day will be the real test.

Since the bore is not any after market material , it is also an OEM , then i dont think u ll get any reliability pblms.

COme on I managed to do 600kms in 7hrs on the stock bore and nothing happend.
Renu did 1700+ kms in 24hrs-Nothing at all happened

So i guess reliability wont be a pblm. Will be same as stock until the metallurgy is same

Oh its OEM? I thought it was not manufactured by Yamaha and was an after market. Can you confirm that Navnish/Joel? I'm pretty sure if its OEMs there should not be an issue with reliability whatsoever. It would be like questioning a CBR if it has the reliability to tour...which it does.

FYI - The 60mm big bore is a after market part. Its not OEM.

Its a after market part.And the quality of the piston and the cylinder is pretty good .

Dont you think if Yamaha had a OEM 165cc bore piston kit they would add it to their so called racing kit ????

thats what i thought..the reason i had that doubt was because navnish said that he was in the process of running in the engine..and i though isnt 120( at a consistent pace) way too high for an engine still being run in?
