Looks great, very unique

First!

Just found this vid, I just bought this bike a few weeks back. Needs a little love to get back on the road. Most of the parts from the build are still on it. It made its way to Arizona.

I owned one of these RC31's before. I believe the big weakness besides way too much engine braking, when you close the throttle. Were the cylinder heads themselves. Originally came on the 500 ascott. Honda just bolted them onto the Nt 650. Something about forgoing emissions testing. Was always curious, never researched it. Honda VT750 also used a 3 valve cylinder design. I've also seen an abomination Hawk with a 2-stroke RZ 350 engine. Two big gains from that was a weight loss of around 100 lbs, and no more abundance of over engine braking you closed the throttle. Beautiful aluminum frame and swing arm is what this bike was blessed with.

How did you like the 663 pistons? Are they 12:1? Why not 696 piston?

Great work on the hawk. Did you press the steering stem out of the hawk triple and press it into yamaha triple to make the stem bearings work?

10/10 always enjoy seeing someone puts their heart into a build

Do you remember the part number for those pistons?

What a brilliant video of a stunning bike totally ruined by the inability to hold a f'ing phone steady!. Got sea sick after a couple of min. Sweet ride but .....

Where'd you find the Hugger ???

Nice. So, what's left over from the Hawk, the aluminum frame?

Can you walk me through what went in to getting the Ducati Monster seat on the Hawk? How much modifying of the subframe, what type of seat/year of ducati it came from? I'm wanting to do a similar mod. Bike looks amazing!

that looks really cool

Headlight and mask are gross, rest is awesome , nice job

Wish you had started it!

hi man, i am looking at a Hawk Gt to do a somewhat cafe racer, brat.. about the nonoarm in the rear, and about the rear whell... can you change the rim no prob, or because it´s a mono arm it wont fit? can you please help me out...

Hey man - Love the bike and the mods !! If you don't mind me asking - how did you find the uni pod filters with the stage 3 jet kit using the cv carbs ? I've read a lot that pod filters on cv carbs can be quite turbulent ? Does the bike rip all the way thru the throttle range ? Thanking you in advance mate - C (I have a nt650v deauville streetfighter and i'm wanting to do the same with my carbs and pod filters)

Where did you buy the uni jet kit with the uni airfilters? And will any of the r6 kill switches work? Thanks

looks like nug at the top of the screen @2:05

HELLO I HAVE A HONDA BROS 400CC (THE SAME BIKE ACTUALLY ) WAHT BACK SUSPENSION DO YOU WEAR ?

Good job on a legendary motor. This motor has win 10 times Paris-Dakar!!!

Unless you just happen to find a sweet deal on a front end (got my R6 front [~$700], Fox shock [~$400], and titled bike [~$1000] all for $800 total) I would just look for a Honda front end. Most Honda bikes use pretty standard dimensions on their front ends. From what I have seen/read, frames have the same stem sizes and thickness on the frame. Do your measuring and research and you'll be able to make it happen.

All it needed was a "custom" set of steering head bearings. If you call up all-balls and tell them what frame you are trying to put what front end on, they will let you know what bearings/bearing kit to get for what you are trying to do. The R6 has a longer steering stem then most Honda bikes. This made me have to put a bit of a spacer in (an inner race from an old stem bearing) to take up the space between the top and bottom triples.

Thanks! I love the work and the pleasure of riding it! Nothing like parking next to a bunch of newer bikes, sitting about 20 yards away, and just watch as people walk up and try to figure out what it is.

They are UNI pod filter... Don't remember the Diameter off hand, but I think I got them as a bundle package with the dynojet stage 3 carb kit.

that air filter brand and model you installed?

80mm u mean .80 thousenths

Absolutely beautiful bike. The best looking Hawk I 've ever seen hands down.

For the yaymaha r6 front end, did it fit nicely without any mods? Did it fit like a 954 cbr/cbr 600 would fit?

just got a 89 hawk gt. i dont know where to start. it hasnt been started in over ten years. any suggestions

Thanx a ton dude. By chance was your key switch aftermarket? The bike I just snagged has one with 3 posts which is certainly not stock.the diagram is perfect tho

Here is a decent layout of what I used. Might have updated a few things here and there as I was working. I posted a link to the description.

hey dude, is there any chance you can draw up a diagram of your harness? I'm basically going to have to gut my wiring after something shorted somewhere and I can't find where because the PO did a hack job on it. That would help a ton. Thanks in advance.

Sounds BADASS!!!!!!

Thats sick man, im getting my second hawk on 650 (actually a BROS) did you have to do much work to get the seat and front end on ?

Hello! incredible bike I have Honda Bros 650 I want to ask where they buy TrailTech Vapor dashboard, Fabini Hugger, Stage 3 jet kit, Uni Pod filters? I find very useful information in HawkGTForum, but failing to register to see all photos Sorry for my english Greetings from Bulgaria and Merry Christmas.

@rollcage9710 Haha... sorry it was like 3 am after putting in like 10 hours working on that bike that day. I was wired and in desperate need of sleep, but I o so wanted to record those videos so they could upload to youtube overnight.

@CHARLIETWW Not that I really would like to think about it, I probably have close to $3500 into this bike with EVERYTHING (price of parts bikes minus sold off parts). When I fix up and sell this other bike as complete for $1500ish that total price will be less... the way I justify this in my mind.

@CHARLIETWW Its only worth it if someone pays. Depending on what is done and the quality of the work to the bike... it might be. But you can get a beat up stock Hawk for not too much if you look. The first hawk I bought was $100 and needed a new countershaft. So I bought a pretty sad Hawk for $700 but it had a motor with only 3000 miles on it and swapped the motor. Then I found a incomplete project Hawk for $800 and took the R6 front off.

I also saw a1988 Hawk GT on sale on Craigslist at San Diego, California for $3,200 firm. Is the price reasonable? Is it possible to get one at half of that price?

Your Honda looks really really unique and nice. How much does it cost to do all mods? It now looks like a naked super bike priced above $10,000.

looks good man! i got sea sick watching, but it sounds sweet!

it just takes a 9V battery to power the sensor bar. and there is only two wires. the red goes to the positive and the black to the negative and your good to go. Wireless sensor bar!

@Celco217 thats awesome dude post a video of it when its finished

@08Street14 This thing looks even sicker now. Its got a 2008 R6 front end and the Ducati Monster tail with the sub frame slightly lifted. Looks like a mean naked GP bike. Its all apart right now getting paint on everything and a 663cc Wiseco piston kit and port and polished heads.

looks good im glad to see people still willing to buy somethig most people wouldnt look twice at and turn it into something that turns heads five stars bro good job

Can you put clip on bars on one of these? Nice bike

lol exact thing happend to me my cat chewed my cord lucky i had about 30 $ to spare i ran to best buy and grabbed myself a wireless sensor bar...to bad it takes about 6 double A battery's and it last for a month lol
