The Hawk 650 was (and probably still is) a popular track bike. I still vividly remember a rider on one slipping past me with ease on the inside of turn three at little Talladega many years ago.
Sold my 96 900 Monster . . .
What have you gone and dome now Tony ? Dusty
Sold my 96 900 Monster to my good friend Petris Rocks as he is known here...Picked up a bargin prices 89 Honda 650 NT aka Hawk GT. Sohc liquid cooled 52 degree V twin, about 58 hp, 405 pounds with gas in the tank. The bike appears to have been abused, dents in the fuel tank, different color parts, cobbed exhaust and ran poorly..The good was a new o ring chain smooth brakes, the engine is sound and a good rear shock. I attended to the CV carbs, a cleaning, pod air filters(stock air box mia) and jetted properly, Mikuni mechanical pulse pump to replace the noisy electric pump. Adapted an Ebay $50 muffler, sorted out a million small issues..... The engine now runs like it should, quiet mechanically and no smoke...The bike is fun on the back roads.decent power at moderate rpm. Not too busy , 75 mph is 4700 rpm...With the offset crank the engine feels like a 90 degree V twin...A cheap substitute for a late model V7, lol
I never knew they existed until about a month ago when a saw test report ...Yes, they are a cult machine but 3000 bucks can buy a nice stock bike..With a good after market slip on muffler, pod filters with rejetting thay can do high 12 second 1/4 mile times. I was interested because they have slower steering than the Monster that suits my old age...lol Pulling dents out of the tank right now using a 50 Amazon buck dent pulling kit with glue on tabs..Works pretty good taking your time with a bit of metal working knowledge.
CW or CCW?
"IIRC, CV carbs tend to have a tough time with pod filters due to turbulent air flow. If you notice this, PVC tube around the air filters seems to help. " I put pod filters on an 81 Honda 750, Ducati 900 Monster and this Honda NT, all have CV carbs. Never experienced the tuning problems people talk about....Besides jetting and float level , The CV chamber vent tubes need to be routed to an area of non turbulent airflow..Right behind the carbs works for me...I also jet leaner than most.. I sent you my email for the article, Be interesting to read, thanks
The Honda has Uni foam pods, the Ducati and Honda 750 used K&N.....The Ducati was very fussy about about the vacuum chamber vent locations. Some vent into stock air box, some like the Ducati have separate filters for the vents. CV carb slides are controlled by air flow through the carb and not manifold air pressure, aka vacuum. In some installations, a bit more restriction to air flow may help tuning, like a partial covering of the filter as you mentioned..Many enlarge the air bleed holes in the slide that determine how quickly the slide opens or closes. Do it wrong and the you you create fuel mixture issues. On the Ducati the engine responded the same to a cut away air box lid or large pods..I used pods to eliminate the bulky box and making jetting changes much easier...and didn't butcher the airbox The Honda 650 NT came with no airbox, just the small cheapo gauze filters. The Honda makes noticeably more power with pods ,some bikes do better with the stock airbox..It's a snotty little engine with the pods and low restriction muffler.
Yes, more intake "honk" with the carbs directly under the metal fuel tank...I wondered if the Africa 750 engine would fit...
friend of mine had a ~1978 Honda Hawk 400cc automatic. F'ing thing was brutalized and indestructible. Great bike.
My friend Joe and his wife Carol just completed a 2000 mile trip on their NT650s.
That’s great to see..
