That head will bolt onto a YX140

The GDFP has built a few of these and has had awesome results.

I dont know what the exact number where but there is a considerable amount of power to be gained with this head.

 

This kit is not just a head though I was wondering if the whole kit will go straight on with ease and would it be reliable with a stock bottom end

Thanks for the reply!!

 

Yup bolts right on and gives 40~45% increase over the factory setup

 

Cheers and do you know if the v2 head will bolt straight on top of my stock cylinder And be reliable??

 

How much is this kit? Who carries it?

 

We have both types listed
TB V2 heads for 50-110cc small pattern
TB V2 heads for 120-150cc Round cam cover / larger stud pattern

i Race Grasstrack here in the uk, Riding in a class called GT140 the Guys who run the TB head are flying. an Ex Australian speedway Rider Glyn Taylor is putting these Engines Together and this year gor the top 3 podium places.

you can see the Difference once they hit 3rd Gear they fly. we basically Ride on oval Grasstracks and speedway and gear to use 1st 2nd and 3rd gears, you can see the speeds on you tube where i put up onboard videos. search Grasstrack GT140

the Engine i use is one by a company called ooracing.com which has a polished,ported and skimmed head the Electrics ie stator coils are all to produce a bigger spark with a High compretion piston, i also Run a 26mm Nibbi carb as per ACU Rules. and the TB Heads are still much quicker. im looking at getting A TB Head and Piston fitted on my spare Engine. but i Beleive Head is £520 the Piston that Glyn has worked on is £80 plus £35 for him to put together
