Building a GPZ1150 from a CSR1000

Did you buy the new shocks... Sorry, I flipped through this post pretty quick.

The company I beleive makes these is YSS. They are made in Thailand. The price is almost a third of other radial valved shocks out there.

Looking at the G-Series.

I'm considering these as well so really interested in any feedback.

No I did not buy the ones in the picture, those were much too short. The shocks that I did put on thare are new hoever, they are aftermarket for a Honda Goldwing. They are 1.5 inches longer than stock. Due to the two inch longer Suzuki swing arm that is on the bike. If however I can find shocks of that tipe at the link you sent me, that are long enough, I will buy them.

Thanks for the descriptions. I have the tail, now I just have to find the seat. Is that the gpz seat or another one you found? How do you find this stuff?

That is a GPZ seat bought on eBay. Than I just cut and modified the pan with a Dremmel tool.

Personally have not spoken to them. Derek (Moto Lab) has discussed these to be build to suit from the NJ rep. I too have aspirations to fit a different swing arm, but later. It's important to work with a company willing to make mods to their products. These guys seem to have their act together.

Pending my current repair bill and expected budget well have to see. At the moment I want to get the bike back in working order.

Of course the over all plan is to sell these new legs to the wife as required safety equipment.

I do have some interesting news though. When I rebuilt the new carbs, I followed the standard rules of jetting. I increased the jet size one for the header and two for the pod filters, winding up at 135cc/m jets (#135). I set everything else according to the book. ( I ignored the posts that people write about pod filters on CV carbs). I rode the bike for two weeks. The bike ran a bit hot, idle was a bit rough and I could not get the engine to go much past 6200 revs. I was getting a consistent 80mi per 1.74 gal of gas. This is a round trip to and from work and is exactly the same every day and will give a very accurate reading. This calculates out to 45.97 MPG fuel economy. Last Saturday I decided to re-jet again and do some other adjustments. First I Opened the idle screws from 1.25 turns to 2 turns outside and 2.25 inside cylinders. Than I replaced the jets with 147.5cc/m. Right away I noticed the idle being very smooth and that I had to turn it down a full turn on the thumb screw. The engine was also running much cooler. now for the good part. The top end RPM now goes as high as 8800 revs and she pulls much harder. I checked the gas mileage for the last two days because I expected that it just went down the drain. Well here it is 1.69 gal per 80 mi. this comes out to 47.34 mpg. Both days the fill up was exactly the same. The next step it to increase the main jets to 152.5cc/m. and get the top end revs where they should be. I will leave everything else the same. The statement, that "CV carbs do not like pod filters", is nothing more than a bunch of bull S**T. Just listen and "feel" the carbs out and it can be figured out how to make things work.

Well- My previous statement stands. CV Carbs will definitely work with Pod filters if the individual doing the tuning is willing to think outside of the box. Since everything on a carburetor works on vacuum, it must be realized what is being changed and by how much. Than everything must be compensated. As long as all adjustments which are made are in some way reversible don't be afraid to try it. You can always go back. One interesting rule of thumb is, The less vacuum a motor produces the larger jet might have to be used. It must also be realized that CV carbs are not designed for drag racing. The fast response acceleration which is achievable with manual slides will never be the same with CVs. BUT for a bike that is ridden every day, you will almost double your gas mileage. The top end of the bike will also not be affected between the two stiles of carbs.

Hi Guys
It has been a long time since I have last posted. I put almost 10,000Mi on the bike last year and rode it till almost Thanks Giving. I am now ready to start doing some more work on it again. I have been very busy at work and just have not had a chance to do much. Well here are my next plans for it. I plan on putting a "Venolia" 1150 12.5:1 kit in it, and a set of Web-Cam #110 cams. I was originally going to put a set of 109 cams in it which I also have but I think that it would not be as street friendly. I do have the 84 ported, flowed, and polished head ready to go. I believe that a well flowed head with the 110 cams will be more than enough. I also picked up another set of carbs for the beast. I decided not to go with smooth boars since my fuel millage will drop threw the floor. I will put on a set of BS36SS CV Mikunis from a GS1150. They have a stage 3 kit in them and at regular riding I can still retain most of my gas millage. I am sending out an extra set of Jugs next week to get punched. I also found a ready made front light to accept my HID system, which I never mounted last year because Xenon bulbs do not work in regular reflectors.

Here is another shot of the reflector from the front.

Fore some reason, my right front fork started leaking again, even though I rebuilt the set, mid last year. I than decided to get a new front end from a 84GPz with the Anti-Dive system. The forks are 1mm smaller in diameter, so I will have to install a .020" shim around them since I do not want to change the triple-tree and the handle bar mount. I got the front end last week and still have not had a chance to check out the seals on it yet. Since I almost never use my rear brake, I have a tendency to bottom out the forks every time I come to a rapid stop. This is why I decided to mount the more modern front forks. I have also decided to mount a Garmin GPS system in place of the Spedo. Garmin has a fantastic Spedo screen that I just fell in love with.

Here are some shots of my new head. It has some massive ports, and according to "Cavanaugh" should give a quite a bit more HP. In stock form a 83-84 GPz had 120hp. This head flows 20% more, the cams will have quite a bit more lift and a bit more duration. Plus the 12.5:1 1150 kit. I think about 150hp should be reasonable for the street.
I will post some pictures of the head work later today.

WoW What a bea-utiful bike. Awsome work!!
