Custom Vintage Style Bobber Project

PostAuthor: hidalgo.ceo » Mon Mar 20, 2017 4:49 pm

Getting Ready to remove the ais system ... want to know if those 90's unthread from the head? If so, are those normally willing to come out or should I find some sort or cap as many others have. I want to run the KjS. Single carb manifold and make the engine smoother, and simpler.

Also if I remove the fuel pump and convert to single tank petcock setup besides the jet in the carb and fuel plumbing is there anything else I have to worry about.

Also I want to put another rear wheel on the front the 15 inch 5 spoke. After looking at it with reasonable machining it seams do able to keep the dual front breaks. I spoke with cafe 750 and he said possibly if some things like fork distace and available space were the same his kit may be adaptable. Has anyone swapped the 15 inch rear wheel on the front. If so is there a kit availale like the first gen kit?

Getting ready for a custom exhaust depending on price will dictate how extreme I go. Could I use standartd car exhaust pipe to the head. Like would a muffler guy with creativity be able to use standard exhaust pipe to get new curves from the front of the motor or should I connect to stock pipers under battery box to the rear. WOuld he be able to adapt or create a flange that will work. going for a upswept exhaust in the rear but want to move exhaust from under bike to the side. of motor for clearance.

The AIS pipes won't come out of the heads. I cut mine off flush with the fins and TIG welded a plug in them.

I don't know all about the 110 fuel system, but think you will lose the lower tank, and I'm guessing you already have, with no pump.

So guys I am at the point where I am getting close to finishing up this project. My biggest task at this point is modifying the factory rear wheel on the second gen 1100 to mount on the front while retaining facotry dual disk breaks. The front hub is roughly 9 inches in diamter on the drum side the front wheel width is 5 inches wide and the rear wheel is 4 ,so my idea is to get with this machinist to machine down the drum side to cleare the left side caliper and have him weld a plate or make adapter to run front rotors, as well as compensate some how for axle differnce.

I was wondering if the 8 cell lithium batteries give anyone problems. I want to remove the plate the old battery sat on and mount it flat under the seat. will removing the plate have any structual effects? I love the idea of seeing the back of the motor and swing arm move as I ride it. I am removing the fuel pump does that effect the need for cca.

Since I am removing the fuel pump I figue I switch to a 700 gas tank and run an idian larry style side tank
style gas feed since the kjs system is side mounted should be highly visible serviable and accessible. When I do this can i just roll up the old pump wiring and hide it and will this effect the gas light in anyway, if so not a problem I will install sight gauge on side of tank or should I retain factory 1100 tank and modify it? and will this effect ignition timing as I am getting rid of ais system as well. Any suggestions on caps or the elbows

thanks

I tried to post pics it said the resolution was too high. I don't know how to post them . Looking through post I saw that some one used a cm400 gas tank on the bike looking it looks like it may fit. I believe the member 67camaro is no longer online. does anyone know if this is a direct swap.

He suppiled a photo but did have fab skills and never discussed if it required alteration on his part to mount.

I have a cm400 tank on my bike, it's not a direct fit. You have to weld new mounts for the front, the back essentially just bolts up. I also clearanced the tunnel of my tank with a hammer to get it a little lower on the frame. If you have a welder it's very straight forward. In the second pic you can see the new mounts just forward and up from the originals.

I want to install battery with bolt on bracket that takes place of service stand but can be removed for reinstallation of stand. The lithium battery seems like the option due to the fact of size but have heard horror stories about what happens if regulator is a little off. I am removing the fuel pump due I still need a battery with 350cc thats normally a 12cell or can I now run a 8cell.

I want to remove the factor tach and speedo/fuse block cluster. I have tried reading up removing speedo/tach on the replacing it with a new fuse block seems to be the answer but now that I am removing the assembly I'm worried about moving wires as I want a much cleaner headlight area but am nervous at the thought of rewiring the bike.

I found an 84 700 with spoke wheels will they swap over to a 94 1100 much easier way of doing the fat wheel conversion by rehooping front.

WIll xv700 gas tank swap directly as I am getting rid of pump and I'm running a single carb i wanted to swap but after I feel like a dished tank will do the same.

I am also swapping to foot clutch.

I have tried posting pics but have been unsuccessful.

just an update to what I have done

cleareanced fram to allow for 170/80r15 whitewall to be used. I am using a burly slammer shocks but spoke with rep had him cross reference progressive shock number to give me proper spring rate. had machinist make collars to adapt from burly imperial to metric collar sizes red did brakes using ebc shoes. and painted rear section black using chassis expoy. Shaved rear fender to side mount tailight. polished rear wheel and sissy bar supports. I am trying to keep the space under seat clean and empty. I feel like a battery box from ebay will make battery mounting easy with some angle iron using stock service stand mounting points.

If i can uses the xv700 tank the carb setup becomes much easier. And I want to use progressive front springs on forks if I can rehoop xv700 wheel. But I am a little worried as xv700 is an 84 model.

This bike I am building is kind of an old school bobber but I feel like lowering the bike really made the rear nice. giving the sissy bar a 45 degree slope.
