Adapting to 17" CBR wheels?

[nsrrider_imp]

This bike is around 550lbs. Taking off a 10lbs centerstand won't help much. I said I'd take mine off but after using it and remembering how helpful those things are. Especially cleaning and adjusting the chain. I saw a review on youtube of a guy scraping saying it was the centerstand. It's not. It's the front peg. I ride mine in the twisties a lot. It's the peg.

Not sure what you're looking for but if you wanted an 80s bike that won't have carb issues and good brakes you found it.

Only stuff I've done is brake lines (huge improvement) a full exhaust, a tune by Guhl (other huge improvement), desnorkeled and K&N , and some shocks and it made it a freighttrain. I love it.it's no cbr1000rr but that's not what you buy a CB for. It's a fun bike.

Don't mind me asking which brake lines did you use?

"Not sure what you're looking for but if you wanted an 80s bike that won't have carb issues and good brakes you found it."

that's pretty much what I'm looking for, plus the simplicity and uncluttered nature of the CB appeals to me. It will probably not get a lot of miles and will be available to friends to use when visiting. But like I mentioned, it would be more than the 10 LB centerstand I would be removing with a diet....full exhaust (15 LBS?), lithium battery (8 LBS?) rear passenger pegs and a few other incidentals.....should gain me more than 30 LBS, just like adding about 6 HP.

Can you tell me more about the Guhl tune? Benefit, cost etc thx

The space issue with the 160 tyre had to do with the centre stand not the swing arm. You may have to lose the stand.

helpful, thx
My bike is on a (slow) truck coming from Austin...it's in AZ now. My build project included losing the center stand anyway. Seems like one of the complaints of the CB1100 is that it's rather "portly." Being the weight-nazi that I am, I plan on a diet for the bike. Looks like it won't be hard to lose 25 LBS. BTW, I'm not trying to turn this bike into a sport bike (I have one)....just trying to optimize its potential without destroying its character or looks.

I have tried to make my bike the most pure 1980's look I can- combined with the best performance.

I always like watching build threads- so make posts so we can see what happens with your bike!!

I've had several cars that I have gone *nuts* on weight loss. But this bike isn't something you are going to loose anything remotely close enough to make any difference in performance on- especially given the cost.


I removed the dumb side trim under the seat- no need for them, look silly, not true to the style and age of the bike. Slight weight saving.

Different battery could save you a couple pounds, not much. Lipo don't like cold weather though.

You can buy an aftermarket aluminum but works same as stock swingarm from Samurider.com that drops weight. Awesome piece- but not cheap.

Easiest weight loss is in a full exhaust system- and will gain performance.

This bike will never be anywhere near 'lightweight', nowhere near great 'handling', nowhere near 'powerful'...compared to the best in each bikes of those categories.

That doesn't mean you can't improve on each- and doesn't mean it isn't a great bike.

The combination of look, comfort, combined with modern fuel injection, gearing, better frame design, brakes... to me is *perfect*.

The bike just needed a little help from what Honda built. But as a UJM- we each can make it our own 'universal' way.

Personally I absolutely would not screw around with different wheels, upside down forks, etc for that goal, but that's just me. More chance of screwing things up, money, time and work spent- for no real benefit.

I prefer to focus on what the bike is- improve those attributes without compromise.

I upgraded to, and highly recommend- the 2017 forks as they are much better than what the earlier bikes have. Others have followed after me and also give the upgrade a thumbs up.

I installed Ikon rear shocks (Ikon is Koni backwards- they sold off the motorcycle division in 2001 so the name was changed in a simple way- but they are Koni shocks). You can call or email them to get different spring weights if you want, various different spring caps, spring colors, adjustability options, etc.

There are several other brands of shocks you can buy- these just looked most period correct to me, and backed by a company with a storied history of making shocks for race cars since WWII.

On my bike- I have a 4-4 exhaust sitting here waiting to be installed, and some secret parts currently being made overseas to bring the power up yet again.


Old pics & old dyno compared to a stock 2017.

And here for the sound is an old video of the 4-1 on the dyno, muffled by the ventilation hooked to the muffler, fans in the room, and small indoor concrete room itself- but still sounds good. Better soon on the 4-4-

good looking bike....and great HP/TQ gains too....
25 LBS weight reduction is undoubtedly attainable...at (around) 5 LBS per HP, that's the equivalent of gaining 5 HP without getting into the motor. It all comes down to power to weight ratio.....and what you want your motorcycle to be.

 

[the Ferret]

Dont forget to add on the weight of the rider. Bike isnt going anywhere without him.

So a bike with a 165 pound rider gains 7 hp advantage over a bike with a 200 pound rider... right?

yes, all things being equal with identical two bikes producing identical dyno numbers, the bike with the 165 LB rider will out accelerate the bike with the heavier rider.

Found this on the net:

“
IKON Suspension is an Australian company that has been manufacturing Koni design shock absorbers under an exclusive license agreement with Koni since they stopped making motorcycle shocks in the year 2000. While carrying on the deep Koni heritage and reputation, Ikon also proudly continues R & D, not only improving their legacy products but developing new ones as well. Ikon shocks are ridden and raced all over the world by motorcyclists just like you.”

I've actually been in touch with them about rear shocks, they were kind an helpful but due to Covid it takes months to get an order out

Guhl does no more tuning. EPA put a stop to it. And not just them.

They still tune.. "Track use only."

Here is what they say: Fuel Injection Conversion - Guhl Motors

Just don't tell them. I literally had mine done like 4 months ago.
They can tune but only for track use. There's ways to have it done. Just not posting it public. But if uou're scared of the EPA don't do it.

I have the Konis on mine. Good shocks. 4 way selector for damping. Look close to stock but handle way better.

As promised, I caught the bike in the shop and as I suspected, the 17" wheel fits in the original swingarm, bearing had to be changed and spacer modified, it clears the notch on the chain guard by 3mm literally. The speed sensor is lost though and they are still figuring out what to do about it, most likely he will change the whole instrument cluster and put everything aftermarket. Hope this gives you some insight

very helpful, thank you!

 

[pekingduck]

If you haven't picked up a used CBR1000R front end and wheels yet, you might look for an ABS model. That will have a speed sensor on the front wheel, so should plug into the harness and solve the speedometer problem.

But it won't show the speed with the front wheel in the air. You wouldn't do that, would you?

 

[rtmoto1]

in regard to the speedo sensor with the rear wheel swap i retained it by machining a carrier for the sensor ring quite simple

Could you maybe take a picture of it for reference, and explain the works for others who might want to do the same?

[Henrik_imp]

If you want to save weight on wheels, Samurider has these mag wheels which not only look great and are made for the bike, but they do save about 10 lbs of unsprung weight. I think that might be quite significant, and something I have considered for a while. It is the price that has kept me from doing the change...

They come in gold, black or silver as well: https://www.samurider.com/?p=26675

Still, JPY 380'000 is like $3'500!!

 

[peterbaron]

You are correct Henrik, very nice & ready to install wheels...... not the price tho U$3,500

 

[misterprofessionality]

I think the issue there is theyre still 18" wheels. The stated purpose of all this was to get 17s.

That said, he'll probably spend almost the same amount of money changing to 17s as he would buying those magtans.
