Hello all,
So I am about to start ordering parts for my bbk. I have been very tempted to try the cheaper ebay kits but I dont wanna have a ton of problems or worries. So I think Im gonna order my stuff from scrappydog.com, Im looking at ordering:
100cc Big Bore kit- 50mm, $89
Performance Big Valve cylinder head assembly - $124
Performance A9 Camshaft - $39
Total $- $255
Being a college student $255 is a lot to spend but Im thinking these would be quality parts that wont fail. Would that thinking be right? The perfromance big valve head is very expensive but from what Ive learned on here it sounds worth it. Are these good prices for these parts and is the quality good? I know to get any more speed I would really have to do gears to but Ill need to save up some more for that, but figured while Im in there I might as well do the a9 and head.
Thoughts and opinions welcomed! Thanks guys

Yes thats what Ive heard teddy554 on the ebay kits. Luckily I have a scooter shop about .5 a mile from my place for jets and odds and ends.
I know it varies from location and engine and all but what would be a good jet to start with?

Yes it is a 49cc.
Thanks millsc that is a good savings.
That stage lll looks like a pretty good deal too though. I know it all depends on rider weight and area and all but is 7g rollers a good starting point? My current ones are getting worn I think. I took them out and weighed them and they came out to be 5.6g so they must be 6g. Does that air filter work with a stock carb or would I need to get a bigger carb for that? My carb now I believe is the stock 18mm, its a stock replacement from my local shop.
Anyone know if the stage lll is cheaper on scrappys ebay store?

I dont buy anything on E-bay. the rollers seem to work good i put the ones in on the kit and im having carb trouble rite now but i put on the stock carb to see if there was a differance and didnt notice any and i never changed the jets. the air filter works real good a little hard to get on the first time the reason i bought the kit was it had alot of the stuff i was going to get anyway the jet is still in a bag never used it got the 22mm carb and it worked great my 2 cents |

Devo344a, do you know if the performance air filter with the stage lll kit helps performance at all? I would think it would easily breath better that the stock intake. But if I used this air filter would I have to do an exhaust too? Cause at this time I dont wanna spend the money for an exhaust.

Ok everyone, finally ordered my parts. 50mm bbk, big valve head and an a9 cam. Unfortunetly a9 is two weeks waiting for a boat from china and the big valve head is 3-4 weeks out waiting for the machinest. Ended up not getting the stage 3 kit because I got the 50mm bbk for 69. and stage 3 didnt seem worth $50 for 35 dollars in parts haha. Ill report back when I get it all and install it. Thanks guys! |
