Hi All,

I am about to fit a Dynojet Stage 1 Jet Kit to my 1990 Honda RC30. It is standard apart from a full race, straight-through exhaust system. Rather than drill out my original slide lift holes, I bought a second hand set of slides to work on. When they arrived, I found that they have already had the slide lift holes drilled out. Checking with the drill bits supplied by Dynojet, I can see that these holes are the larger #30 size drill. The Dynojet instructions recommended using the smaller #37 size drill and the #30 for racing.

Please can anyone with experience of these kits tell me what difference is there between the two when riding the bike please? Does a larger hole mean a more aggressive slide lift? I want to use the bike mainly for sunny day road riding on fast open roads and potentially an occasional track day. Will the #30 slide lift holes make the bike difficult to ride on the road?

Thanks, Ian

For everyday riding the standard lift holes are best. In my experiance however the drilled lift holes do improve peak power between 8,000 and 12,000 rpm by between 2-4hp.
