What sprocket combo for my motor?

[fauxamish]

First, I did search and found some threads, but not really what I was looking for. That being said:

I am in the middle of a rebuild and I need to know what gearing you think I should be running. The engine is now a 416 with 11:1 compression, stage 2 hot cam, 450r carb, K&N filter. I will be doing a lot of MX this summer so I have 18" tires. My current gearing (this is what came on the bike when I bought it...) is 13/39. I think this will be too low, so what do you think I should be running? I was thinking of going to a 14 in the front. Any input is greatly appreciated.

i would say try the stock 15,38. I like it alot. with my 416. it pulls hard and will not just wheelie all the time. I think it would work great with the 18" tires since that is like running a stock motor with stock tires and a 14 tooth. you could try a 14, 38 and see how you like that with the new power. it would rip too, it depends on what the track is like. if it is a longer track go with the 15 if it is tight and technical try the 14. Just my .02 though, Steve

If I did 15/38, I could still use a 94 link chain?

try 13/36

[honda400ex2003]

you should be able to use the 94 link. That is the stock length right? I dont remember off hand. I have the stock length on mine. steve

I know the 99-04 and 05+ have different gearing, but the splines and all didn't change right? I was looking on RM and they have a 15 that would fit 05+ but doesn't come up for my 2000.

[honda400ex2003]

I have heard that they are different both some also say they are the same. I am not really sure. you should be able to find a 15 for the old ones. at least primary drive and renthal should have them. I have a 14, 15 and a 16 renthal and a 38 rear renthal with my did x ring and they fit on my 03. sorry I cant tell yopu for sure, steve

[fauxamish]

Yeah, I am only asking because RM has them on sale for $5.25 but I cannot get a 15 unless its for 05+

[honda400ex2003]

WOW GOOD DEAL!!! sorry i cant help you out, i guess you could buy it and see if it does not work you could sell it on ebay or on here. steve

the threads on the 05 are different than the ones on the 00-04 i ment the splines.

The splines are different? or the threads for the retainer thing?

[hypersnyper6947]

The splines are different they are bigger and there is less of them, compared to the <04'.
