How about the other kind of "gears"? As in, 21t 4th gear or close ratio 3rd - 4th gear.

Can anyone share some experiences after upgrading their gear box, any recommendations, positives or negatives?

sir marcus can help sir...i think he already tried diff sprocket that are compatible.

ride safe...

stock 4th gear is 23T, you can change it to 21T(KITTI or YYPANG). as per my observation, it runs smoothly with 15 - 44 and 15 - 42.
for city driving, im using 15 - 45, long ride 15-42.

hope this helps.

I've heard someone is selling 21T gear here in our Forum.

Thanks

Thanks bro marcus for the input.

I'll see if I can find a bigger rear sprocket, currently using 15/41.

Does changing 4th gear to 21T peak rpm at lower speeds on the top end? Same effect as a larger rear sprocket?

IMHO changing gears from 3rd to 4th after having 21T increase to reach top speed at a lesser time.

Maybe almost identical in having a larger sprocket, Didnt experience that though cause before having 21T the largest size I've use is 42t.

After the engine modz, I experiment from 15-40, 15-42, 15-44 and now im using 15-45. but for stock engine 44T up is not recommendable unless you will use 16T in front to lower the ratio.

Hope this helps

thanks bro, i'll be in watch mode for awhile on this topic until i'm ready to do some engine mods, just thinking how much "flavor" to add to the recipe.

yap, how come those exclusive foods are so expensive, haha. But I think big poppa is a good chef, he can make very flavorful recipes at a discounted price, like eating at turo-turo or dampa.

4th gear

@ Marcus, Blue: Nope Im not the seller but I do have one for sale hehehe.
I have a lot of inquiries but no takers yet :D so there, its a kitti 21T for anyone who is interested.
I will be trying close ratio 3rd and 4th gear soon, Its not for sale though and haven't installed it yet so I can't say anything about its pros and cons. Thanks Bros!

Question @ Marcus: I noticed that those are low speed combi bro (+/- 2.8 ) that you prefer. Of course that is with your 4th gear set, and I assume CDI and 149cc+ block. Have you tried High speed sprocket combis (2.65 or lower)? What was your observation? Thanks boss, appreciate your sharing. :D

@Big Poppa, I am more into acceleration bro for city driving. the lowest gear ratio i've tried is 2.66 15/40. tops at around 140kph. Havent tried lower than that.

It's more satisfying for me to have a good acceleration cause there's no long straight here in our area.

current tyre is battlax 90/80 F and 100/80 Sport demon both these tyres are over size, there will be a plus in speed if i will change it to 80/80 and 90/80 in front cause the load will be lesser, lesser ground traction = to high speed.

thanks

Thanks bro.. road conditions here in my place and to work (where I use the bike often) is actually more on highway driving than city, thats why I asked about the Hi Speed combis..with the fourth gear. (im not using 4th gear and sprockets are at 16x43) Appreciate your reply Boss! Thanks againl

sir mark question.... for stock engine with modifications such as pipe and cdi... will changing the gear for the 3rd and 4th or 4th gear is acceptable or not? meaning will the engine suffer or not?

just a query because there is no power on the 4th gear and i think we need to change the gear for the 4th to be able to feel the kick and push of the engine

Yes, you can change 3rd and 4th gear, even 4th gear alone 21T but the price for changing that is much expensive than buying the gear....ha ha ha....
