big difference. the ttr seat height is 30.5 inches. the yz seat height is 39.5. that's 9 inches difference.
14.8
a lot about 20mph
A ttr 125 actually has about 14 hp. That's not that much but it goes about 70 mph an hour stock!. TTR125 is a great bike,.!
whenever it is fulli use 1 and a half quarts in my 03 yz125
CRF150 BY FARRR - I had a ttr125 and sold it to get a crf150 and the enormous difference is shocking. The reason is that the ttr125 is a trail bike with a small engine. its acceleration and hp are decreased so that the bike is safe on trails. The crf150 if it ends in R or F like crf150R or crf150F - the F means it is a trail bike as well but it still has much more speed than the ttr not to mention size. the crf150R is a race bike made for the track and therefore it comes with a non spark arrested pipe and it is very fast for being a 150. check these out http://powersports.honda.com/2009/crf150r/specifications.aspx http://powersports.honda.com/2009/crf150f/specifications.aspx http://www.yamaha-motor.com/sport/products/modelspecs/238/0/specs.aspx
the manual says for a 32:1 ratio, but a 40:1 is good just dont go with too much more gas in the mixture than that
Look on the side of the engine by the oil filler. It should read the amount in cc's or ml's. It would be around 900 cc's of oil (1 quart is 946 cc's).
i think its 650 cc's. it also should say on the clutch covering by the oil cap. my manual says for an oil change is 21.98 oz.
Fuel/air too rich, or way too much oil in mix.
