I guess they are the right ones Thanks Drewpy.

I've got a '74 TX500 and since I've never had very good luck with the KEIHIN carbs I went ahead and bought a set of Mikuni 38's from a later XS500 (38mm). The carbs came with 30-Pilot/122.5-Main, I'm trying to make sure that these are within the range that are suppose to come on the XS500 w/ mikuni carbs. Thanks!

Michelin Pilot 2CT, no question. (Or the Pirelli Corsa III's, basically a similar dual compound tire). Great looking bike btw!

That's hard for me to say, I ride an early aprilia that probably has one of the ugliest front ends known.

I agree that the front fairing of the '09 R1 isn't easy to look at BUT the bike is a mechanical masterpiece; it will clean the floor with a Duc 848 and the 1098. The '07/'08 R1 is still very nice, no complaints there if the buyer wants to save some dough to pick up one of these over the '09. The new R6 is leaps and bounds ahead of Suzuki. Besides, we're talking about quality motorcycles here.

ugh, you'd have a lot more fun with the R6 than the GSXR. Either way, it's your money and your decision

The R6 is going to be a much easier bike to ride; it's slightly more nimble and doesn't have as much low end power. For someone with just a years worth of riding under his belt it might not be 'worth-while' to pick up a new R1 just yet. If you don't like the idea of putting the money in to savings until you feel the urge for a new bike you could consider modifying the R6 to your taste.

I'll sell you one, you can make yours a parts bike Speed and Sport has a lot of NOS parts: http://216.168.60.165/speedandsportinc/index.tpl

If the carbs looks identical to the ones below then I have a bunch of spare parts. Floats $20/ea You could try Speed and Sport (http://216.168.60.165/speedandsportinc/index.tpl), they usually carry NOS parts.

can we just get to the point?

found it, 180 degree phased twin. hmm, anyone know if the part the points cam mounts on is 8mm, similar to that of the xs650?

Does anyone know the firing orientation of the TX500 engine? 360, 180? This is one of the questions Pete is asking me.

Right now I think I want to stick with the Pamco system BUT I will definitely take a look at the HPI site for consideration. Thanks! Emailing him now, Thanks!

I want to put a CDI ignition on my '74 TX500 but all that I can find are for XS650's. Are the points systems any different from each other? I am looking at the Pamco Electronic Ignition Kit on http://www.mikesxs.net/mikesxs-electrical....category_id=2.1

I did rebuild the carbs when I got the bike but the kit I got through S&S did not come with new jets. I dropped the bare carbs off at a local shop to have cleaned (they put it in some machine that vibrates the part in a solvent). The points look great and last I checked the timing was spot on, I'll check the dwell. Just an FYI, the engine has just over 700 miles and it starts and idles just fine when it's cold.

Alright. One carb was set about 3.5 turns out and the other was wayyy out at around 5-6 turns. I took out anything I had covering the filter so that I could get the fuel set properly. I started the bike, let it warm up and used the idle set screw to get the idle around 1750-2000 rpms. From there I adjust each 'air screw' out (from a gentle seat) until I reached the highest idle that I could notice and then turned it in a 1/4 turn. As soon as I let the idle screw down the bike would hover around 1000-1100 rpms and eventually die after a few seconds. If I leave the idle screw set just high enough to keep the bike running the rpms want to hang for a little when I give it gas. The 'chugging/stalling' feeling when I begin to use the throttle from idle is still there and this is somewhat magnified when there is load on the bike (i.e moving from a stop). Anything else I should check? I've changed the plugs with NGK's, the points look great, but I never touched the wires...would that be causing a similar problem?

I will verify where they are set and compare them to that setting (as a reference). I would prefer mikuni carbs but at this point in time I am not up for the hassle of a conversion.

I have yet to touch the mixture screws so I am unsure if they are at oem specs or not. I can check to see where they are set and try a turn or two clockwise to see if that helps. The engine is a 500c inline twin. Two (absolutely horrible) Keihin carbs.

I had a previous thread regarding my '74 TX500 and some issues I was having with it. Well, now it's pretty much road worthy with the exception of a slight idling issue. The bike starts up fine (on choke or without when cold, no choke when hot) and idles great when it's cold. Once I take the bike out and it gets warmed up it always feels like it wants to die when I let the rpm's settle back down to idle (just above 1k). It use to die like this all the time until I restricted the intake filter a bit (wrapped some cloth around it somewhat decreasing breath ability) and this seemed to help. I have figured that it is probably just running lean at idle/under 4k rpms (pilot jet) and that restricting the filter somewhat helped. It doesn't like it when I abruptly give it a lot of throttle from idle (chugs or dies). Is there anything I can do before I resort to swapping out the jets that might get the mixture a bit more rich? The carbs are clean, floats are spec'd, etc. The bike is 100% stock.

The flat black one definitely appeals to me, wow! I'm not a fan of a 'flashy' bike but I can definitely respect the work you've put in to it!

Looks and sounds great! I'd love to get my hands on a swing arm like that for my TX.

you should modify that slip on like I did on my R6

I'm sure it will do just fine as a commuter bike but I am pretty sure your R6 makes more low end power compared to the newer engine in the '06; many people talk about the '06+ as having a very peaky powerband.

The seat height is much higher (33.5"). Fly-by-wire throttle system. There is less mid-range power but more top-end power although the redline is raised to 17.5k. 2006 had some suspension issues that were fixed for the '07+ Great bike if you are tall and don't mind the lack of torque.

Dunlop Qualifiers -decent performance, longer life or Michelin Pilot 2CT -dual compound, good performance, long life or Pirelli Diablo/Dragon Supercorsa -great performance, short life *When I owned a 2004 R6 I put Qualifiers on it at first, great tire for the decent rider. Once I got better I changed to the supercorsa's and my confidence went through the roof.
