Tuning Qlink Pegasus 150

[bond007]

For those interested in tuning a Qlink Pegasus 150 I think I've got a couple of good ideas for you. I cut the muffler off at the point where the big part of the muffler is, at the front. After the 1 inch pipe graduates up to meet the larger Muffler. I bought a 3 inch Inside diamater Glasspack from Summit racing. It is 4 inch on the outside and muffler part is 18 inch long. It comes unfinished so you do not have any trouble painting it with High Temp Flat Black Paint. Used a Recirculating saw, with blade for hard steel, to cut with. Cut of all the bolt nuts behind the crome sheild off. Hardest part to cut because the welds are so tough. I went through about 8 - 6 inch blades total. Cut of the pipe ends on the glass pack and welded it to Old muffler brackets and remainder of pipe. Welded a Crome Tip, I got at Auto Zone to the end of muffler after cutting of the 3 inch end piece. Put back on the original crome sheild on the glass pack. Oh by the way the Pegasus has a power robbing catalitic converter in it. Not worried, No Emission checks in Indiana except in a couple of big cities. When finished it looks like the Original muffler with a fancy crome tip. Cool. A freind helped me with the welding because I do not have any Mig welding experiance. I rented the welder from a local Tool rental place for $30. Muffler was 40.90 with shipping. Blades for saw About another $25. Paint $5 Total $100.90. Not bad considering what a new muffler cost. Can not buy an upgrade muffler for the Pegasus150 anyway. Also Installed a Dial-A-Jet before Carb. Much to my surprise, Qlink put a fine Japanese 26mm Mikuni butterfly Carb on the bike. Now here is what I did not expect. I gained 7 Mph top end. ;D ;D Gloat! 77 on the Spedo and my tires are lower for comfortable ride but not low enough to be dangerous. I'm told spedo is optomistic by 3%. That's as fast a most 250cc scoots claim to be. And that was in cold 30 degree weather and windy. Should do a little better on a good day and higher air pressure in tires. ;D
Dial-A-Jet, really did it's job well. And You can acess it through the opening for carb Idle adjustment under the seat. Very surprised at relatively High Performance Improvements. So was my mechanic welder freind. ;D ;D David, P.S Like Steve McQueen, All I need a fast machine, an I'm gona be allright. Wo Hoo Hoo , Cheryl Crow

That is pretty cool.
I am curious as to how many RPM's does it turn at 77mph?

I don't know but it does not sound out of the ordinary to me. When they are wound to tight I just get a bad dangerous feeling. Sounds crazy but my dad was a Sprint car driver till mom made him quite. I used to race motorcross back in the 70's. So I kind of Inherited racing skills. I feel pretty confident It would be happy to run at that speed, but not for hrs at a time. Then again who knows. I want to keep the bike for a long time and spend most of my time at 60 and below. It will do that all day I'm sure. The bike just has that solid as a rock feeling like all of those hondas I used to have. Gearing ratios are quoted in the manual is it possible to figure an estimate on paper Earl? The final gear ratios are written in some funny form that I do not understand. You would first have to know how to compute it to an american standard. Then I still don't think you could figure it out mathmatically with out more Info. Later Earl, David ;D ;D

Man, how can you post something like this without pictures? Outstanding!

Its not nice to gloat but I dont blame you---that sounds like a nice set up! I would like to see some pix, too, cause thats the same engine thats in my CFMOTO--I just might have to give it a try. Did you try driving it with just the muffler mod and not the Dial-a Jet ? Is it much louder than stock? Art

It's is much louder than stock. I could never hear the stock setup and would always end up driving to fast. Plus the new setup is a little on the loud side probably for some. I ended putting a crome muffler tip on to tone it down a little. The muffler tip has a smaller opening on it. Sorry no digital camera to post pictures. I just can't stand to drive a motorcycle that you can not here. Hearing the engine purr a deep tone is music to my ears. That is why I selected such a large 3 inch dia glass pack. 4 inch on the out side. You see it is a little like a pipe organ, the larger pipes make the lowest tones! It looks totally stock to average viewer. I doubt that your 2004 has a catalic converter. That's good from a power stand point. The police do not mind around here if you have loud pipes, because they know it is good protection for the motorcyclist. You can really notice how much quicker people notice you. I was surprised that it would make that much of a visual differance. Yes I did drive it a little without the Dial-A-Jet. It was running to lean and slower, which is what I expected. Also the average running temp was up on the temp guage. Another sign of a lean condition. Dial-A-Jet fixed it right up. I'm sold on the product, although the web site does make a few to many positive claimes, particularally about the gas savings issue. Don't see how improved milage can come into the picture when you are jetting up. David
