+2 Had to have been an incredible time. Run what you brung? For sure!
Newer V-Max V4 engine converted to chain drive?
That blue RD is sublime.
More eye candy from Campbell CA.
Cr 500 super moto with electric start and aluminum tank.
This will be raced tomorrow at the Sears Pont Kart track.
Then of course the Holy Grail: VJ 23
Other notable bikes in attendance; RZ 350, CBX, Benelli six cylinder.
My friend Joe is attempting to sell his RG 500 Gamma this morning. Asking price $42,000. Insane. The guy who is looking at it just bought an RZ 500. 0 kilometers, in the crate from Japan. Either it is time to sell or hoard!
Edit: the guy paid $42,000 and he would have paid more. An RG 500, with more miles, went for $50,000 at auction in Vegas recently.
Got some work done in garage yesterday, as the weather was a bit cloudy and wet. Put the Zeel ignition in the Aprilia RS, and started to put the billet heads on....but the domed nuts do not fit over the long studs. Head is about 1/8 shorter in dimension to stock, so open end nuts it is...
Ignition looks easier than it was.
Weather was nicer today.
So, since I haven’t actually had a chance to just ride around for a week or so, I opened garage door and picked a bike to ride.
The RZV was the short straw, so I set choke, moved out kick lever, turned on key, and kicked it to life. Sounded good, so I checked each pipe....then noticed only 3 were smoking
Upper left cylinder had a carb float needle stuck closed....or I am pretty sure that is the problem...
I said fuck it, and went to my VJ21 SP, and it fired up and was smoking out of both pipes....warmed up, and took it out for a brief thrashing.
I’ll get back to the RZV after I get the RS250 done, and the CBX ready to sell. Have to pull the carbs off that and clean them out as well this next week.
Old bikes are cool.....but whatever replaces the CBX’s spot will be a 4 stroke, and fuel injected....Im getting to point riding is more fun that wrenching....
Maybe Aprilia RSV4, BMW 1000RR, Suzuki GSXR1000.....something with way too much HP, for an old guy...(close to 200).....6 more payments left on the 1290SDGT....
Suzuki GSXR1000,,,got one,,,lov it,,,,but man thos pegs are up tight on my 2005.
The 08 SuperDuke 990 is what I am 'bout to jump on for a ride today...and put more than 100 miles on it yesterday.
Need to see if I can get some bar risers and drop the pegs on the GSXR to get it closer to the SuperDuke ergos....what a motor on the GSXR.....and always ready.
I’ve done several CBX carb cleans.
Hit me up if you want any tips and tricks.
(I’d rather do a CBX than a V Four)
Thanks for the offer, but I have had the carbs off quite a few times in the past 25 years of ownership.
When I put the 1147 J+E big bore pistons in about 5 years ago, I pulled EVERYTHING apart in the carbs, and even replaced every single seal between each carb as well.
But it has been over 5 years since that rebuild, and I think they probably are probably lined with green slime in some areas.
Holy shit that is a lot of parts
Here I am delving into my first engine rebuild and I am only working on a single cylinder.
Love the way you laid everything out on the timber base, nice one.
The CBX has all the same parts, just times 6.
Pulled CBX carbs today....will clean them up tomorrow. One stuck float, and some junk in the bowls from what I initially see.
Pipes on the RS, and fired it up to make sure ignition worked....it did.
But looks like a crack in one of the pipes...?
Busa, awesome thread!
I’ve been sitting in the hospital for the last 9 days on oxygen due to post COVID pneumonia. I’ve passed a lot of time drooling through this thread and it really almost feels like I’m hanging in the shop with you. Takes me back to the mid 80s when I worked in a Yamaha and Kawi dealership and would occasionally see a stroker of some sort roll through.
Been a lot of fun, thanks for the work you put in with all the posting!
Hope your past the worst of it, and making a comeback to health. Friends of ours just tested positive for covid yesterday, although they got the vaccine 4 months ago.... They are not doing so well.....
Motorcycles help make all the insanity, and problems around us....disappear. Sometimes long enough to find a bit of happiness
Sold the CBX a week ago.....haven't missed it yet, so that's a good thing.
I think it went to a good home.
Since the money came from something in my garage....it has to be reinvested into something else that is in the garage already.....or something I want in my garage...
Spent more time on the Aprilia RS250 this week.
Got it running after getting the pipes on, and warmed it up so I could get the air out of the cooling system, and let all the oil that had leaked into the crankcase from a leaky valve....burn off. That showed me that my Zeel was working as designed, so I put the Dyna coils and 8mm wires on.
Then I pulled the carbs and put in 310/320 main jets in place of the 270/280 mains, because I had a carbon fiber airbox that needed to go on.....the company said to up the jetting because of the increased airflow.
But the bike didn't run as good as it did with the 270/280 without the airbox in the midrange.... I am so tired of trying to tune 2 stroke carbs.
So not sure to drop the mains and see what happens, or richen up the midrange....airbox company said that was not necessary...
On a good note....I have a date set for some dyno time with my VJ21 SP, so I can see what the Lectrons are doing for HP....or what they are not doing.
The 29th of this month...as long as it doesn't rain.
Some 2 stroke torture....
I was at the 2 stroke extravaganza today in Valencia, CA. I walked past this bike a couple of times before I realized it wasn't some party crashing 4 stroke heathen:
There was also one of these. I think it is lacking from your 250 collection. For shame.
There were plenty of other cool strokers. Mine weren't there, unfortunately.
The KR1-R is the rarest of all factory SP 250’s
Not much was different from the S version other than 35mm carbs...but if you can verify a genuine R version, you have found some gold $$$ no matter what part of the world it’s in. Last I saw one was for sale in Japan about 4 years ago...way over $10,000 even then....and it was in as raced condition...
Less than a few hundred EVER built.
Dyno Run been pushed back a few more weeks....weather, and free time on the dyno the same time I can be there is the hold up.
I could drop it off and pick it up in a week....but I need to be there. Plus I’m not leaving my bikes anywhere besides inside my own garage.
Work on the RS250 has slowed to a stop til I figure out why one cylinder is only firing about 20-30% of the time.
I figured I would fire up my FZR and run some fresh gas in it.... Obviously nothing goes as planned, and after screwing with it for a while I figured out what the issue was.
The o-rings on the needle seat valve were leaking...flooding the bike, and fuel going in the ground. Fell apart pulling them off. Luckily I had some old seats with good o-rings on them and swapped them out... need to see if I can find more o-rings this exact size for spares.
Fixed....just in time for more rain...
Hopefully I can get it out yet this week and burn off some cobwebs.
At least they were easy to remove.
When I offered tips and tricks for the CBX carb rebuild I was unaware that you no longer had an airbox...since with the airbox in place it's a bit of a challenge.
