plus I'm only using a TZ7 battery... although i did fit double size battery cable which sped the starter up considerably.... I have an '04 model... 110,000km ridden very hard and I've just lost 3rd gear. Luckily for me I purchased an '17 Gen3 engine with 12km on it... thought it might come in handy one day and that day has arrived... I'm putting the Wiseco kit in the new motor...If there is any difference it would be small given virtually identical size. Just curious, why do you ask?
Yeah OK... the Gen2 engine did 110,000km ridden hard... still ran perfectly however it lost 3rd gear.. selector dogs... which is a bummer as that motor is now basically worthless now.That sounds like fun!
If you get a chance in the future please give us an update on how you like it.
