nice Terry,what rpm does it turn on the highway?no tach on mine.bill

Mine sits at around 3,000 but its a 4 speed lol
mine is 4 speed too,guys, some time it feels like it could use an od gear,but other than that it will pull from low down in any gear.terry they claim that the 5spd was better at slower spds.bill

Could be Bill, but they're such a torquey engine I suspect it had more to do with marketing....... ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

I (only just) got mine up to the "Ton" at Christmas Tim, it pulls really well up to about 80, then runs out of puff with the overly lean stock CV carb.

My project is to double the stock rear wheel horsepower over time, it's already got the Screaming Chicken mufflers, so should be improved with the Mikuni HSR42 carb when it arrives. My engine's only done 4000 miles in it's 22 years so I don't want to do any major surgery yet, just little mods.

Like you, I've got much faster bikes, so it's not like I'm starved for scary fast thrills........... ;D

Nice! My neighbour's kid has a pretty rough early R1 rotting in his driveway, I've been tempted to make him an offer for it, but I just can't squeeze another bike in my garage at the moment..... ;D

Oil pump restore with Elan oil pump kit. Waiting for new countersunk bolts M6 x 60.
I do not like the X bolts and they dont like me. I took them out the hard way with my drilling machine and various sizses of drills. That worked fine, not a scratch on the pump.
Now only hex bolts and the countersunk ones will have allen heads. Pump has to wait for rest of the engine that is not yest out from frame and opened. It will get another crank, trans and better clutch parts.

Thanks Frank, the guys over on the Sporty and Buell forums say that a better carb and less restrictive pipes makes a huge difference to their performance, and even reduces the vibrations by a fair bit, so I'm looking forward to the new HSR42's arrival. I was hoping it would have arrived by now, but no biggie, plenty of other bikes to work on...... ;D

Heres what we did..stretched swingarm 4 inches.. This can be optional..
1200 kit.. Back then it was stock 80 inch big twin pistons and a template the hemi the head..gonna grind for a while.. Todays dropin pistons may elimnate that part .
 We removed airfilter, put cover back on.
 Mounted the mufflers in the mill,cut out the main baffle... With a hole saw.. Allows you to weld it back in ..throathy,but still some baffle so you can ride on the street.
 Not sure if we touched the gearing... Thats all we did to it.. Maybe rejetting..

Thanks Frank, mine's an XLH1200, I don't want to do any internal engine mods just yet, but I must admit I'd love to take it out to 100 cubic inches, (1640cc) eventually. I've been looking at prices of donor engines in the US, and I've seen some for around $1K, so eventually I might import one and stuff it full of S&S big bore kit, cams, heads etc. I'd love to just buy a whole S&S engine, but they're silly money.

That's a nice old R1 Tim, where'd you score that? Cheers, Terry. ;D

I finally got around to figuring out the rest of my electrical issues. I had no front brake light signal and my horn has never worked for me. Turns out "as usual" it was 38 years of corrosion...cleaned the switches and housings and now everything works as designed.

Sorting out the electrical relocation(under-seat), went on check-out ride(she likes 60 degree air) everything looks good. Now its time get everything permanently mounted. Next big project is the fiberglass seat pan and cowl. Oh...and I tested some new riding gear, ATGATT. ;)

I swapped the wheels back on the 2 400F's. Yellow got it's original wheels and new ties back so Red can have the new rims, tires  and spokes.

Finally got the clutch adjusted to a sort-of-acceptable pull. It still gives me a workout but I can live with it I guess. Can't wait to meet owners of other CB's so that I can compare with their clutches.

Last week I changed the flat bars the previous owner installed to Renthal low bars. At the same time I got rid of a third party start switch and got the original one working. Took me 3 attempts to make the little bracket but persiverance paid off.

Broke it!



Went out to do a nice ride through wine country...clutch stopped working 15 miles from the house. Had AAA come to the rescue and get her back home. The cable was iffy when I got it, will order a new one tomorrow and start taking her apart.  :(

Must be more than clutch cable?
No problem to drive without cluch as long it is not sliding and maybe too much city driving with redlights, green lights OK :). Elecric starter with gear in, change gear when release throttle just when the gearbox is unloaded between acc to dec.
