Who makes it?

Looks like a bhp intake

I have no idea I got it from atvguy. that dude keeps amazing me with his stashed parts

I'm pretty sure BHP intakes are 4 bolt

v force 3 ordered today

Douglas, you ordered the 3's thinking it would solve the alignment problem?

you are right Joe the bhp intakes do not have the center bolts

this is a new problem to me. been almost 7 years since I started to hoard parts for this bike. also this is my very first 250r. not once have I ever seen a post or a mention of the carb alignment. I am amazed that there was never a topic of conversation that I ever picked up on this. being a big bore ESR cylinder in a stock frame apparently seams to be a fitment problem. there seams to be a matter of opinion on this to run the spacer or not. Arlen built my motor I did not speak to him about the carb alignment till I had already bought the V3. I sent him my ESR reed block for him to install with the build. when he looked over what I sent him and said what carb I had and what type of riding I did. he made changes to the engine build. # 1  he did not want to use my OEM stroked crank that ESR did for me. # 2 the carbs I had were not what he would recommend for this build. and he suggested for me to not use the PV cylinder. there was no mention on his part on the ESR reed block. of course at first I questioned the reasons for the changes but Without hesitation I followed his lead. I got the motor back fully assembled reed block and intake installed. I put the motor in mostly focused on not scratching the frame first [ hahahahahahahaha ]. my first priority was sprocket alignment since I was using a 450 swinger. once I addressed most of that I had my shock line I need to make sure there was clearance for the intake. so I tried to install my carb. The ESR reed block I have is the thick one. I posted this information on .net .org and both face book sites. got mixed opinions on it. most expressed that I needed a spacer plate. and with the thicker reed block this only made the alignment worse. I did not know that ESR also has a smaller reed block. thinking the V3 would solve my problem with the spacer only put me back to where I was same alignment. now most everyone is telling me to use the spacer plate. So I called Arlen and talked about this with him. he expressed that on his engine build that the spacer plate does not need to be used. he cleans up all the casting on the intake side. even with all this the carb alignment is not that good. yeah you can make it work I can see that but its still not an easy fit. atvguy gave me the aluminum intake to try on this being that it does not have a built in boot it is to long and the angle is a little better. I have been tinkering with a mock up of a new intake. I made a template and cut a few angled pieces. looking at this from all options. for now the best alignment I see is to run the V3 with no spacer. any advice would help.
thank you

Douglas,  I have been running an esr cylinder for a few years and do not have much issue with alignment. I have an upp intake boot Vforce 3 reeds with a .250" spacer. Im also using a stock airbox boot so that helps I'm sure. I at one time ran without the spacer, but I kept going through reeds. Some do not have that problem. I suggest using a stock boot or a cr250 boot. Do not cut your frame! http://www.imagebam.com/image/0f34cf795045153http://www.imagebam.com/image/43808f795049113

On my 330 pro x cylinder. With vf2 reeds and a stock intake. My alignment was not great. I had to pull the carb down to meet with the intake. I really didn't think of it has much of an issue. It was also a brand new stock intake.

Have u thought about getting the short body carb? It might solve mounting issues. I've always had a miserable time with my 39mm and reedspacer. Never did find the right combo that helped with alignment. I have the VF3 to

yeah I do not want to cut the frame that's for sure. i have the cr boot and 2 oem boots the cr is out it puts the carb towards the frame rail. the stock boot and still is a little out. i just thought there would have been a better option. i am running an LED intake its not so much the intake positin its the carbs position. thank you for the pics. atvguy has 10 fully built 250r's he is only 1 mile from the house. i have looked over all of his set ups.

i never thought about the short body carb. i'm sure it would give more room in this area

i got to get back to my bike and do some more work. today I mounted another tire to one of my OMF wheels I now have the front ones assembled. back to the drawing board on my swing arm. sprocket alignment with the 450 swing arm using the 450 axle is not going to work. I pulled the axle out and put in an 87 250r axle. using the 450 components locking nut brake stay rotor and caliper it all fits. the sprocket alignment is out 1/8 of an inch easy fix with a machined spacer onto the axle. only problem is I would have to purchase a new one as my 87 axle is not pretty. i'm trying to save my 450 axle as I have chromed it and also chromed my wheel hubs. so I removed the sprocket hub off the 87 250r axle to see if it will fit onto the 450 axle. the splines are the same as well as the diameter. the only thing that is different is the 450 axle has a shoulder stop near the bearing race. so the 250r sprocket hub needs to be machined a little on the inner part of the I.D. also the splines are longer on the 250 than on the 450 this is the same area that is going to be machined. the 450 splines are about 1 inch the 250r is about 1 1/4. they are matching on the axles as well so during installation you can push back a little to remove the spring clip. I brought the sprocket hub down to the machine shop to be modified for me. should have it next week.
