Ok iv got a scorpion race can on my bike and apart form that I think its pritty much standard and desperately need more power, The bike even seems to be slower than other standard nc30, as in a side by sude race with a mates bike, also with an end can it lost by about 8 metres to 100mph

I was wondering what are the cheepest modds to get a bit more power out of the standard engine, dont have time or money for engine tuning at the moment.

The bike is a road bike but i do trackdays on it and will also be racing it this year so need all the power I can get.

and yes im not hung up on power, the bikes blinding through the corners, did a td yesterday and wasnt pased by a single bike that wasnt down the strait but all the other 400's their were quicker than me down the strait, but i do have 15 42 gearing so could be a hint as to why.

cheers

try a service plugs air filter etc.....valve clearences,carb balance....binding brakes,it all adds up.

Couldnt agree more....


Try losing weight where you can aswell, you may be familiar but there are plenty of weight saving threads on here to browse through and get ideas...

Have the carbs been set up properly since you unrestricted it and added the can? Other than that just clean it inside out!!

Change the gearing.

^^^^^^ +1


When i was fiddling with my bike for dragging it, the gearing seemed crucial. Its not just that the shorter the gearing the more acceleration you have but you are also doing more gearchanges to get to the same speed. Even if you are doing a clutchless change, its still losing you time.


Try going back to standard gearing and see how it goes and then work from there. If you have another bike as reference, you can find a nice bit of (private) straight road and see how yours compares with different gear set-ups.

Oh, and theres a special race product for making fairings flow better. Theres a few different makes but i find Mr Sheen works quite well. some people think its for furniture but its actually developed for bikes. Hence why its endorsed by Barry.

The cheapest part of the bike to modify is the rider.
Get it running perfectly as a standard bike first, spend time and money on maintenance.
Spend lots of time on the track, until you are using pretty much everything the bike has.
Once you are at that point you will have a good idea of how much more power you need and you may decide it isn't worth the cost of making an NC30 go as fast as what you need OR you may be fast enough as a rider to not need any mods!
How this all works out will depend on the track(s) you spend time on too.

What all the others said: gearing, major engine service, carb setup.

A 14t front sprocket will be more in the ballpark (with your 42 rear) for most tracks.

check the connections for your coils. my bike had 2 dodgy connections which was losing me power.

Go on a diet.......lol.......money you save on food buys more go faster bits.......lol.....

Also check ya tyre pressures, make sure the chain is lubed and right tension, change the fork oil if its not been done for ages. Check head bearings for wear, in general make sure its as near as Honda intended it to be first, it gives you a good starting point for testing mods to make sure your going in the right direction

You spend more time going round corners on a track then going in a straight line so handling should really come first. Unless your loaded it takes quite alot of cash for a few BHP.

If 60 brake and good handling isnt enough your best saving up for a 600 i think really.
