  • GSR46R back from long hiatus.

    Trying this again, hopefully it works this time.
    Hey all, been signed up for a few months but haven’t posted anything. Just built up my GSR46 and figured I’d post a few pics. I’m in SoCal Riverside area, if anyone is near and wants to ride give me a shout! Here is a parts list:

    ESP head, piston match ported myself
    ADA stroker crank
    JetPro Rhino
    ADA billet motor mount/tensioner/black wheels/intake mani
    Toymaker 40 clutch carrier
    8/76 gearing, DDM sprockets
    RAD tank/cover/filler cap
    DDM race pole/steel ftg

    I weigh 185lbs and hit 42 mph without the stroker crank and ported piston. Currently assembling new crankcase with the ada stroker crank and ported piston along with copper base gasket. Hoping for some better low end with the stroker crank/piston. I just need to smooth out/chamfer the piston edges and pull the old motor off/apart. Hopefully will have the new motor set up running soon.

    Nice. I think 2 stock gaskets is recommended when using stroke crank. I used the copper on my stroker but ended up doubling it up because i think I soll recommendation on ada site or ddm

      Your Ped looks great! I’m glad I bought one one the ADA tensioners, works very well. Just took my 460 interceptor for its first ride yesterday! Much faster than my 25 that’s for sure! Front wheel came off the ground in the first 20 feet. Going to need some practice to get used to it!

        Yes they do recommend 2 gaskets, I have a squish indicator tool so we'll see if I need 2 or not. Here is a pic of the new crankcase/crank and piston.

          Yah once I changed the gearing in mine it wants to pull the front wheel up closer to 20mph when the power starts to come in.....that for sure takes some getting used to!

            Running 2 gaskets for your stroker will effectively raise all of your port timings. The thicker the gaskets the more drastic the changes will be to your port timing. The effects may not be what you are looking for but you wont know until you install the stroker and ride it.

            That's where running a tighter squish clearance may help which will likely require the use of race fuel to prevent pre detonation.

            Check your squish 0.24" - 0.31" is THE MINIMUM dont go lower. I believe gp460 stock squish is .041" - 0.44"

            I would try to use the thinnest gaskets you can while remaining in the safe zone for squish to avoid drastic unwanted changes in port timing.

            Or you could avoid all that that just get the ada 460 head kit for the 1mm stroke choose your dome and call it a day.

            Let me know how that stroker effects your setup, nice 460, I too am in so cal specifically Fontana. We should ride!

              Top speed numbers seem low. Ive seen most 46’s hit 45 all day on a stock top end. I weight a the same. This is fully tucked on flat ground tho. Standing upright, I’d probably be more in the 42ish range. However, your gearing is lower than mine.

                Yah I haven't ever fully tucked when doing any speed runs. I am still dialing in the carb but have hit 44mph with the new set up. On 8/76 gearing I am getting about 13,850 max rpms. My squish was .027" with a .020" and .005" copper base gaskets. I mainly have noticed stronger bottom end with the new set up. Before I was only able to get about 13k rpms. I have some pocket bike wheels going on soon so I hear that should give me another 1-2mph. I am happy with how it is running now, I'm not looking for ultimate top speed with this set up as I don't want to loose any low end. I picked up a GTR and I may end up swapping this engine onto it and getting an OBR fat boy or other reeded set up for the GSR. I mainly just want this set up to be reliable and hit around 45 mph so I should exceed that once tuned perfectly with the pb wheels and fully broken in. I only have about 2 tanks through it right now and it feels stronger and stronger each time I ride it.

                  The PB wheels will help with the top speed a lot. Post a pic of those wheels installed! Super interested to see how they look. I was checking those out ended up with the ADA ones instead.

                    Will do, any tire mounting tips? I’ve watched a few vids. Some say simple green/oven, others tire levers/armor all, grease etc.

                      Haha, yea. I did it years ago, and again recently. Forgot how rough it is. There is a trick tho.

                      Rather than shove the rim into the tire, your gonna want to mount the tire on the rim. This means placing the rim on the ground, lubing up the tire (with whatever, soap grease, doesn’t matter) and shoving it down onto the rim. Getting past the first bead is easy-ish. The second bead is much harder.

                      I had a spare rubber for a sport (no rim) and placed it on the ground , then stacked the rim on top of it. Doing this allowed me to step on the whole assembly while working the tire down over the second bead with the tire irons. I found that using your body weight is key, otherwise you’ll find yourself gauling the crap out of your wheels.

                      my wheels were painted, and I got away without a scratch, and even had to mount one tire twice (because I mounted the wrong direction).

                      Ooo that reminds me. Take serious note of the direction of the tires and the location of your valve stems. For my gsr40 frame, I had to mount the rear valve stem on the left and front valve stem on the right due to brake disks and sprocket locations.

                        Well I got the tires mounted, front one went on without too much struggle. The rear took a lot more force to say the least. I just used a thin layer of grease and some plastic tire levers. They have held air perfectly for 5 days now. I’m waiting on a new front Hope brake set and then I’ll start putting them on!

                          Making progress slowly but surely. I decided to go with a new 4 piston set up in the front and just the dual in the rear since you can barely see it anyway. The brake hoses are too short so I have 1 steel braided hose here already, just need to cut and install it on the front and order another for the rear.
