Alright guys, its been a while since I've been on the board, or chat. Hope everyone is doin good! At any rate, the 'ol faithful R had developed a problem.... the last weekend of riding it ran beautifully, not a problem in the world, untill the last day of the weekend (fortunately). It started sputtering out when riding at wide open throttle. I ran the sand hill probly 15 times the night before blasting up at wide open and no problems, went to sleep, got up early went on a long trail ride and noticed it was running a little hot considering the outside temp still hadnt risen too high yet, then I went to do the sand hill and no go, part throttle was ok, and WOT for short bursts was ok, but holding it at WOT it just sputtered out, like it wasnt getting gas or maybe spark. Plus it was running hotter than I thought it should.
Here's what I changed recently... I used to run VP 110 in it, but the place I go to buy fuel now sells FL 111, so I used that for the first time on that weekend, with the same 32:1 Honda HP2 synthetic oil mix that I always use. Right away I noticed it hardly smoked at all with the FL, even at cold start-up and not when I revved it iether, and that was even with a freshly cleaned and oiled air filter, which usually makes it smoke for a while untill it sucks in the excess oil thats on the filter. It also seemed to run a little hotter than it usually does... maybe I should change the oil mix to 30:1 or even 28:1???
Also I changed the throttle cable and put on a quicker-twisting twist throttle, which I like very much, not sure if that would have anything to do with it. Im thinkin maybe I sucked something in the carb that clogged the main jet, or maybe there's something wrong with the electrics, spark cutting out at high RPM? It has a fuel filter and I havent seen anything floating around in there, and I cleaned the air filter before the ride, as I always do, although it was dirty by the last day of the weekend... It also did suck up a little tranny fluid, which it has always done, nothing more than usual though, I guess thats a leaking crank seal? The engine is basically stock, except for a K&N, Outerwears, no air box lid, and an aftermarket silencer. Before the ride I put in a new spark plug, the fuel and oil were fresh, and the whole bike got the usual maintenence I give it before every ride. Before this the bike had sat in the garage for 3 months without being ridden, or started (shame on me). I expected any carb gumming problems would be apparent right away, but it ran great once I got it started and blew it out with the throttle. Maybe the lack of smoking was a gum clogged jet, and it ran so great because it was too lean from the clogged jet?? But why did it run so great at WOT one day and refuse to run at WOT at all the next??
Im thinkin Im gonna have to take off the carb and clean it out, but before I go taking it apart, maybe someone has some ideas? Thanks guys for taking the time to read my loooong explanation. Hopefully I can fix this before this comming Haloween weekend's ride! :)
