Removing the gear up kit will give it more acceleration... your now in the realms of porting, camshafts etc.. |

The malossi digibox is for the leader engine and fits the runner and GT,PM part no.07-M5512341 for models fitted with immobiliser,the PM fuel module is for the GTS only. |

If it is just pull-off that you are concerned about, then how about a set of Malossi clutch springs, which will let the engine rev a bit harder before the clutch takes?
I would recommend the yellow ones (they come in a set of 3 colour-coded grades).

If it's any help I had the malossi cdi on my gt 200 and a pm pipe. Although the acceleration was not as quick as the 250 ( I only had the standard variator) The top end speed was as good as, if not better than
than the 250. I think this was because the limiter never cut in whatever speed I was diong. I still have the cdi and exhaust (I've sold the 200) now got 250. Cheers Graham |
