Just out of curiosity
Where can I find a better price on a new 99 CR 125 Cylinder and a piston kit?
It’s been a while from where I can remember how affordable those parts were.
I’ve been looking everywhere, trying to replace my top end that the Nikasil got removed by my piston failure, and everywhere I’ve found so far is $390 for a new Jug, $125 for Piston kit, $ 85 bucks for the head, plus all gaskets.
In all seriousness. Does anybody know of a more economical alternative? I wanna keep it legal for road racing in Laguna Seca.
P.S. I should mention that my old cylinder already has the Power valve delete kit and blended.
swedetech prepped cylinder @ fastech for around $470 less 10% for the Supernats sale makes that about the best deal I’ve seen…if you want just bare cylinder, no plugs, try partzilla.com for parts, I’ve ordered many times from them with no complaints…99 cylinder is $271.95 from them…that Fastech deal is the best, make sure you mention the 10% off supernats sale to get the discount…its posted at the top of his homepage
I have a DDR prepped cylinder kit which is less than a year old. While it isn’t brand new I never had a failure and is definitely going to be cheaper than new. If interested shoot me an email at email@example.com.
Your jetting will change depending on weather conditions, fuel and elevation.
That being said with out providing a lot more detail in terms of the conditions. I run a 99 stock moto with a dual pump around system and a 170 main will only work at high elevation and a HOT day. Chances are that your main is to lean. I run a 175/55 as my starting point. I have stuck my motor before and it has always been related to a lean condition. Fatten it up… start with a 178/55 or for a new top end break in try a 185/55 make sure to get it up to temprature before hitting it. a little on the hot side is better that cold. Bring the temp up to at least 140 degrees then run it at about 125-130 degrees.
