January 23, 201610 yr Hi all, Anyone have any experience / advice to share on adding flywheel weight to small four-strokes for trials..?
January 23, 201610 yr Personally I wouldn't think a small 4 stroke would need one, they are not exactly arm rippers!
January 23, 201610 yr Author it's more to try and squeeze a little more 'plonk' out of the bike- for mud & inclines..
January 24, 201610 yr yes it would be a benefit with some of those motors, especially when they are running larger bore and stroke that original, but there is usually very little room to add weight
February 22, 20224 yr OLD POST I KNOW BUT... I recently did the 144cc big bore to my TL125. Works great, but not sure I'd go through all the problems again BUT what a difference it made. Now it's making me wonder about the addition of more flywheel weight. I had a friend at a bike shop long ago that would measure id/od and use a sleeve from car engine, cut them to width, freeze the flywheel and heat the sleeve, put them together and produce a heavier flywheel. It worked but you were limited without machining to what ever weight you got, that was it. It worked on small MX 2 strokes to make them ridable for kids. Has anybody tried something like this????
June 4, 20233 yr i have been thinking about adding a little weight to my TL flywheel as well. but not around the outside. could a round plate be attached to the hub of the flywheel around the riveted area? it looks like a 1/4" thick disk could be attached there but i still need to do some measuring. you can do a lot with 9hp and a heavy flywheel. remember those huge steam powered tractors that first plowed the hard packed midwest plains? 9 hp and a heavy flywheel. i don't expect to plow my garden with the TL, but you get the idea.
