First things first, the kits arrived and credit must go to TYGA as everything was perfect.
When fitting the kit I did run into some problems. These were quite easy to fix though. As I was fitting the kit to an MC18, the power valve cables for the top cylinder were a little too long and needed some interesting routing before they cleared everything. I also found that neither plug leads would reach, so new leads had to be made. A new radiator lower mount also had to be made as the stock MC18 one wouldn't fit the 300 barrels. The biggest pain though was fitting the pipes. Quite why I struggled I don't know, but TYGA use angled exhaust stubs which did take quite a bit of time to line up allowing the pipes to slide on and off easily.
Today I managed to rebuild it and ran it all in. I spent a few hours this afternoon on the dyno and came up with some interesting results.
The one interesting thing is out of the two engines... I like the 250 better!
Is that what you call perfect? !!!
Its a good job you are a mechanic as some owners would be pulling their hair out with all the problems you have had.
How come you did not fit the HRC jet kit before you ran it though?
How long did you run it on the Dyno for before doing full bore runs?
On the Tyga site it says "This is a SIMPLE bolt on replacement top end kit which radically improves the power characteristics of your NSR250."
Nice graphs in the end though!!
