I noticed a huge difference with my -4 oz flywheel from trailtech, I can only imagine a ignition paired up together.

Is it only to bolt on a crf ignition on a trx?
No other changes need to maked?

Arnt

side case needs to be machined. thats it. everything bolts right up.

i would also like to know the advanteges i was looking as the sparks kit

Do a little searching, lots of info on the subject here on the forum as well as dyno runs.

Be aware that a dyno can't always show you everything that's going on & a flywheel is a good example - discussion is archived on the forum.

i have it and even though trailtech says it doesn't add any horsepower it does allow the engine to rev a whole lot faster. the seat of the pants feeling is like going from a stock pipe to a full system. It gave my quad a hit that is as hard as a yfz but still smoother then a yfz so it doesn't tire you out. It just revs so much better and it never bogs down in corners no matter what gear i am in. I personally say worth every penny spent.

The CRF flywheel must also be modified!

what do you need to modify on the flywheel , Im machining the cover on friday night and thought that the flywheel was bolt on ?

if your motor is built dont even waste your money, i tryed the trail tech kit on a built trx i had a couple of years ago and after hacking up my entire harness '' you have to in order to install the TT kit'' i did some runs at my usual riding spot racing the same friends with the same bikes and that kit didnt anything whatsoever not even a little for performance, i had to put a little bit of a fight to get my money back from the supplier but i got my $700plus back but i had to purchase a oem stock harness$200 because my original harness was worthless after hacking it up for the install, let me tell you it was a nightmare....... it may be an improvement on a piped or mildly modded bike but i can tell you for a fact that this kit is worthless on a fully built bike
