Is the F.I. reprogrammable on this bike? On totalmotorcycle.com they say its programmable but I see several people on this thread talking about the EJK.

Speedometer error

There's no mystery about speedometer error when changing from the factory 14-tooth to a 13-tooth front sprocket. The error is EXACTLY (13/14*100)-100 = -7.14%.

By fitting a SpeedoDRD and entering the number -7.1 from the above equation, (must be rounded to 1 digit after the decimal point), the error is eliminated precisely. GPS checking has proved to my satisfaction that the very tiny error remaining is due only to tire wear (or lack of it!) and road surface.

BTW, the 13-tooth front sprocket is perfect for the hilly roads on which I ride.

I installed the Ventura luggage rack this evening. Good quality brackets, nice bags.



Installation notes and more pics of the different bags are right up here.

Thanks for the info.

Why is the SpeedoDRD so expensive? $70 is what I've seen.

Radar all over the place around here, and all over, to increase revenue of broke town budgets. Think of the SpeedoDRD as less than the price of a speeding ticket....

A buddy of mine had a CRFL last year (late in the season, I didn't even know he had it!), anyway, he sold it after removing all the goodies he added. I managed to snag the DRD for $40 off him.

No installation instructions for it other than it goes on the speedo-sensor on the transmission case.

An hour later and much swearing, I managed to get it hooked up to the connector in front of the air box mounted on the cross tube. What a PIA!

Nice to have an accurate speedo again though (he had the 13T sprocket as well).

I've been bad though and haven't gotten out for even a single trail ride this year. Bought a new street bike and thats been getting all my attention. To be corrected this weekend at the Calabogie Boogie!

Ah...but with a 13t the speedo will always be reading higher than actual so thats even cheaper

I went to my local Honda/Yamaha/Suzuki dealer to check on the CRF250L. I was quoted $5,600 OTD on a 2013 that they didn't even have in stock..."but we can get it within a week."

They've charged you for the bike, all their processing fees, tax, and all the fees to transfer the bike from another dealer.

Call around and find the dealer they located and just by direct from them. Cut the middle man out.

So i couldn't find anything anywhere with someone modifying the stock exhaust...

So I did it and documented it all myself.

IMS tank

Buddy of mine ordered the larger tank but sold his bike before getting it installed. Offered it to me for a slightly reduced price. If you weren't looking closely at the bike, you wouldn't know you had a larger tank. Really is a nice fit. After installing it, I went to the local gas station and put in exactly 3 gals in a container. The tank took it all plus another 16 oz. This will keep me in the comfort zone when riding Baja in November.

Keep us posted on how many miles you get out of that tank.
