No instructions but rouse garage on YouTube walked me through the install first try no problems
Jerry✓ Verified Purchase•September 17, 2023
It had basically everything you can ever need aside from the big bore, I'm very satisfied I installed it and got it right the first try, make sure you have a tourqe wrench and gasket maker to seal the gaskets and some feeler gauges to set your valves. I'm going to steal a saying from talidaga nights when I say on the first test run I could feel the vibrations! Be sure to tighten bolts after a couple weeks to month back to there specs which is 13-15 foot lbs do your research I know I've never dug that deep in an engine and I ride the he'll outta my scoot, change your oil after first couple rides and then after a week of riding then a month plus get assembly lube for the jug and everything and your do just fine I followed a YouTube video it was rouse garage, takes about 4 hours to install, enjoy!
Nice

This kit had everything I needed and more. Belt came in handy a few days after receiving. If installing a bbk , have a spare belt on you when riding. It might save ya
Good quality and quick delivery

The media could not be loaded. Very good good kit ! It's easy to install with general mechanical knowledge. Took me about 3 hours but was not in a hurry ! Just make sure you use Loctite on Necessary bolts and do valve adjustment and and few heat cycles and your good to go !!!
Works great
