idle at 95 mofo... i need more power to push the gears i want
I had to get a friend in the States to pick up tghe 16 tooth front
for the KLR. All the places here kept telling me no one makes one.
What a PITA!
well... i put on my 16 front, and 42 rear along with a new chain. i like the whole 125km/h at 5500 thing... there is no appreciable loss in acceleration. this thing still pulls fuckin sweet intersection long wheelies with a full tank of gas but i'm thinkin the 38 is gonna be way more fun for freeway cruising
now that i've done this... i have no idea why ktm put the 15 on stock. there is little i couldn't ride with this 16 in second gear. .... consensus is.... the 16 is for keeps!
next plan? 38 on my road wheels and a 45 or 48 on my dirties. i'll let you know what happens.
bump. by request
damn it I was sleeping...
Mine is 16-42 as standard, but I have now got a 15 for the front for dirt use, I suppose I should re jet and stuff, still standard at 8000 miles.
Hi. Can you make this file, or a newer version, available again? I have it, but want to give a link to some others on ktmtalk. I punched in some exc numbers and it was very useful! But, what's a km/h
it might be in my Yahoo Briefcase potato - link in the Index.
pm me yer email and i'll send it to you...
Hey Loaded, did you ever put that 38 on? What was the result?
Now that it has been a while, and you have had time to test the various sizes out, what is the conclusion? Would love to here your take on the various ratios... I am looking for a second gear ratio for highway cruising, when I want to go long distance... is 17-38 too radical?
I'm not Loaded, but maybe I can provide some info:
I ran 17/38 on my '02 640 Adv with a set of motard wheels. Even with the much smaller diameter 17" rear, 17/38 was just about too tall. It really takes a lot of snap out of the performance, and makes uphill twisties a strain. You really have to wring its neck.
The math says 17/42 with the 18" rear (140/80-18) would be comparable to 17/38 with the 17" rear (150/60-17). In my experience, I wouldn't go any taller than that, but I haven't actually tried 17/42 yet.
See post #9, etc.
PS, Holy ancient thread revival!
Yeah, it's an oldy-goldy.
I think magli deserves a pat on the back for finding it instead of starting a new thread.
So, since I do not mind losing performance, as this would really only be a setup for covering long distance, I think that the 17-40 ratio which arch suggests in post 9 seems like a good idea, since it allows for the same chain size.
So, the only question that leaves, before I go and order these parts, is whether it is a bad idea to use the same chain: I was always told that the chain and sprockets should be changed at the same time, etc... would I skrew up my chain if I occasionally changed the sprockets?
Thanks for the replies,
I've never worried about that on dirtbikes, where chains & sprockets are relatively (compared to easy street miles) short lived anyway.
Anyone have a copy of that handy LC4 specific spreadsheet?
Yes, PM me your email address and I will send it along. That will be my penalty for not uploading this stuff to one of two nice people who have offered space on their servers...
i swear i uploaded the spreadsheet i made to my own web site... i'm sure it's in there some place... just where... shit... i''ll look tomorrow.
